test: add Preview3D execution flow E2E tests

## Summary

Harden 98 E2E spec files and 8 fixtures/helpers for deterministic CI
runs by replacing race-prone patterns with retry-safe alternatives.

No source code changes -- only `browser_tests/` is touched.

## Changes

- **E2E spec hardening** (98 spec files, 6 fixtures, 2 helpers):

  | Fix class | Sites | Examples |
  |-----------|-------|---------:|
| `expect(await ...)` -> `expect.poll()` | ~153 | interaction,
defaultKeybindings, workflows, featureFlags |
| `const x = await loc.count(); expect(x)` -> `toHaveCount()` | ~19 |
menu, linkInteraction, assets, bottomPanelShortcuts |
| `nextFrame()` -> `waitForHidden()` after menu clicks | ~22 |
contextMenu, rightClickMenu, subgraphHelper |
| Redundant `nextFrame()` removed | many | defaultKeybindings, minimap,
builderSaveFlow |
| `expect(async () => { ... }).toPass()` retry blocks | 5 | interaction
(graphdialog dismiss guard) |
| `force:true` removed from `BaseDialog.close()` | 1 | BaseDialog
fixture |
| ContextMenu `waitForHidden` simplified (check-then-act race removed) |
1 | ContextMenu fixture |
| Non-deterministic node order -> proximity-based selection | 1 |
interaction (toggle dom widget) |
  | Tight poll timeout (250ms) -> >=2000ms | 2 | templates |

- **Helper improvements**: Exposed locator getters on
`ComfyPage.domWidgets`, `ToastHelper.toastErrors`, and
`WorkflowsSidebarTab.activeWorkflowLabel` so callers can use retrying
assertions (`toHaveCount()`, `toHaveText()`) directly.

- **Flake pattern catalog**: Added section 7 table to
`browser_tests/FLAKE_PREVENTION_RULES.md` documenting 8 pattern classes
for reviewers and future authors.

- **Docs**: Fixed bad examples in `browser_tests/README.md` to use
`expect.poll()`.

- **Breaking**: None
- **Dependencies**: None

## Review Focus

- All fixes follow the rules in
`browser_tests/FLAKE_PREVENTION_RULES.md`
- No behavioral changes to tests -- only timing/retry strategy is
updated
- The `ContextMenu.waitForHidden` simplification removes a
swallowed-error anti-pattern; both locators now use direct `waitFor({
state: 'hidden' })`

+# Hardening Flaky E2E Tests
+
+Fix flaky Playwright specs by identifying race-prone patterns and replacing them with retry-safe alternatives. This skill covers diagnosis, pattern matching, and mechanical transforms — not writing new tests (see `writing-playwright-tests` for that).
+
+## Workflow
+
+### 1. Gather CI Evidence
+
+```bash
+gh run list --workflow=ci-test.yaml --limit=5
+gh run download <run-id> -n playwright-report
+```
+
+- Open `report.json` and search for `"status": "flaky"` entries.
+- Collect file paths, test titles, and error messages.
+- Do NOT trust green checks alone — flaky tests that passed on retry still need fixing.
+- Use `error-context.md`, traces, and page snapshots before editing code.
+- Pull the newest run after each push instead of assuming the flaky set is unchanged.
+
+### 2. Classify the Flake
+
+Read the failing assertion and match it against the pattern table. Most flakes fall into one of these categories:
+
+| #   | Pattern                               | Signature in Code                                         | Fix                                                              |
+| --- | ------------------------------------- | --------------------------------------------------------- | ---------------------------------------------------------------- |
+| 1   | **Snapshot-then-assert**              | `expect(await evaluate()).toBe(x)`                        | `await expect.poll(() => evaluate()).toBe(x)`                    |
+| 2   | **Immediate count**                   | `const n = await loc.count(); expect(n).toBe(3)`          | `await expect(loc).toHaveCount(3)`                               |
+| 3   | **nextFrame after menu click**        | `clickMenuItem(x); nextFrame()`                           | `clickMenuItem(x); contextMenu.waitForHidden()`                  |
+| 4   | **Tight poll timeout**                | `expect.poll(..., { timeout: 250 })`                      | ≥2000 ms; prefer default 5000 ms                                 |
+| 5   | **Immediate evaluate after mutation** | `setSetting(k, v); expect(await evaluate()).toBe(x)`      | `await expect.poll(() => evaluate()).toBe(x)`                    |
+| 6   | **Screenshot without readiness**      | `loadWorkflow(); nextFrame(); toHaveScreenshot()`         | `waitForNodes()` or poll state first                             |
+| 7   | **Non-deterministic node order**      | `getNodeRefsByType('X')[0]` with >1 match                 | `getNodeRefById(id)` or guard `toHaveLength(1)`                  |
+| 8   | **Fake readiness helper**             | Helper clicks but doesn't assert state                    | Remove; poll the actual value                                    |
+| 9   | **Immediate graph state after drop**  | `expect(await getLinkCount()).toBe(1)`                    | `await expect.poll(() => getLinkCount()).toBe(1)`                |
+| 10  | **Immediate boundingBox/layout read** | `const box = await loc.boundingBox(); expect(box!.width)` | `await expect.poll(() => loc.boundingBox().then(b => b?.width))` |
+
+### 3. Apply the Transform
+
+#### Rule: Choose the Smallest Correct Assertion
+
+- **Locator state** → use built-in retrying assertions: `toBeVisible()`, `toHaveText()`, `toHaveCount()`, `toHaveClass()`
+- **Single async value** → `expect.poll(() => asyncFn()).toBe(expected)`
+- **Multiple assertions that must settle together** → `expect(async () => { ... }).toPass()`
+- **Never** use `waitForTimeout()` to hide a race.
+
+```typescript
+// ✅ Single value — use expect.poll
+await expect
+  .poll(() => comfyPage.page.evaluate(() => window.app!.graph.links.length))
+  .toBe(3)
+
+// ✅ Locator count — use toHaveCount
+await expect(comfyPage.page.locator('.dom-widget')).toHaveCount(2)
+
+// ✅ Multiple conditions — use toPass
+await expect(async () => {
+  expect(await node1.getValue()).toBe('foo')
+  expect(await node2.getValue()).toBe('bar')
+}).toPass({ timeout: 5000 })
+```
+
+#### Rule: Wait for the Real Readiness Boundary
+
+Visible is not always ready. Prefer user-facing assertions when possible; poll internal state only when there is no UI surface to assert on.
+
+Common readiness boundaries:
+
+| After this action...                   | Wait for...                                                  |
+| -------------------------------------- | ------------------------------------------------------------ |
+| Canvas interaction (drag, click node)  | `await comfyPage.nextFrame()`                                |
+| Menu item click                        | `await contextMenu.waitForHidden()`                          |
+| Workflow load                          | `await comfyPage.workflow.loadWorkflow(...)` (built-in wait) |
+| Settings write                         | Poll the setting value with `expect.poll()`                  |
+| Node pin/bypass/collapse toggle        | `await expect.poll(() => nodeRef.isPinned()).toBe(true)`     |
+| Graph mutation (add/remove node, link) | Poll link/node count                                         |
+| Clipboard write                        | Poll pasted value                                            |
+| Screenshot                             | Ensure nodes are rendered: `waitForNodes()` or poll state    |
+
+#### Rule: Expose Locators for Retrying Assertions
+
+When a helper returns a count via `await loc.count()`, callers can't use `toHaveCount()`. Expose the underlying `Locator` as a getter so callers choose between:
+
+```typescript
+// Helper exposes locator
+get domWidgets(): Locator {
+  return this.page.locator('.dom-widget')
+}
+
+// Caller uses retrying assertion
+await expect(comfyPage.domWidgets).toHaveCount(2)
+```
+
+Replace count methods with locator getters so callers can use retrying assertions directly.
+
+#### Rule: Fix Check-then-Act Races in Helpers
+
+```typescript
+// ❌ Race: count can change between check and waitFor
+const count = await locator.count()
+if (count > 0) {
+  await locator.waitFor({ state: 'hidden' })
+}
+
+// ✅ Direct: waitFor handles both cases
+await locator.waitFor({ state: 'hidden' })
+```
+
+#### Rule: Remove force:true from Clicks
+
+`force: true` bypasses actionability checks, hiding real animation/visibility races. Remove it and fix the underlying timing issue.
+
+```typescript
+// ❌ Hides the race
+await closeButton.click({ force: true })
+
+// ✅ Surfaces the real issue — fix with proper wait
+await closeButton.click()
+await dialog.waitForHidden()
+```
+
+#### Rule: Handle Non-deterministic Element Order
+
+When `getNodeRefsByType` returns multiple nodes, the order is not guaranteed. Don't use index `[0]` blindly.
+
+```typescript
+// ❌ Assumes order
+const node = (await comfyPage.nodeOps.getNodeRefsByType('CLIPTextEncode'))[0]
+
+// ✅ Find by ID or proximity
+const nodes = await comfyPage.nodeOps.getNodeRefsByType('CLIPTextEncode')
+let target = nodes[0]
+for (const n of nodes) {
+  const pos = await n.getPosition()
+  if (Math.abs(pos.y - expectedY) < minDist) target = n
+}
+```
+
+Or guard the assumption:
+
+```typescript
+const nodes = await comfyPage.nodeOps.getNodeRefsByType('CLIPTextEncode')
+expect(nodes).toHaveLength(1)
+const node = nodes[0]
+```
+
+#### Rule: Use toPass for Timing-sensitive Dismiss Guards
+
+Some UI elements (e.g. LiteGraph's graphdialog) have built-in dismiss delays. Retry the entire dismiss action:
+
+```typescript
+// ✅ Retry click+assert together
+await expect(async () => {
+  await comfyPage.canvas.click({ position: { x: 10, y: 10 } })
+  await expect(dialog).toBeHidden({ timeout: 500 })
+}).toPass({ timeout: 5000 })
+```
+
+### 4. Keep Changes Narrow
+
+- Shared helpers should drive setup to a stable boundary.
+- Do not encode one-spec timing assumptions into generic helpers.
+- If a race only matters to one spec, prefer a local wait in that spec.
+- If a helper fails before the real test begins, remove or relax the brittle precondition and let downstream UI interaction prove readiness.
+
+### 5. Verify Narrowly
+
+```bash
+# Targeted rerun with repetition
+pnpm test:browser:local -- browser_tests/tests/myFile.spec.ts --repeat-each 10
+
+# Single test by line number (avoids grep quoting issues on Windows)
+pnpm test:browser:local -- browser_tests/tests/myFile.spec.ts:42
+```
+
+- Use `--repeat-each 10` for targeted flake verification (use 20 for single test cases).
+- Verify with the smallest command that exercises the flaky path.
+
+### 6. Watch CI E2E Runs
+
+After pushing, use `gh` to monitor the E2E workflow:
+
+```bash
+# Find the run for the current branch
+gh run list --workflow="CI: Tests E2E" --branch=$(git branch --show-current) --limit=1
+
+# Watch it live (blocks until complete, streams logs)
+gh run watch <run-id>
+
+# One-liner: find and watch the latest E2E run for the current branch
+gh run list --workflow="CI: Tests E2E" --branch=$(git branch --show-current) --limit=1 --json databaseId --jq ".[0].databaseId" | xargs gh run watch
+```
+
+On Windows (PowerShell):
+
+```powershell
+# One-liner equivalent
+gh run watch (gh run list --workflow="CI: Tests E2E" --branch=$(git branch --show-current) --limit=1 --json databaseId --jq ".[0].databaseId")
+```
+
+After the run completes:
+
+```bash
+# Download the Playwright report artifact
+gh run download <run-id> -n playwright-report
+
+# View the run summary in browser
+gh run view <run-id> --web
+```
+
+Also watch the unit test workflow in parallel if you changed helpers:
+
+```bash
+gh run list --workflow="CI: Tests Unit" --branch=$(git branch --show-current) --limit=1
+```
+
+### 7. Pre-merge Checklist
+
+Before merging a flaky-test fix, confirm:
+
+- [ ] The latest CI artifact was inspected directly
+- [ ] The root cause is stated as a race or readiness mismatch
+- [ ] The fix waits on the real readiness boundary
+- [ ] The assertion primitive matches the job (poll vs toHaveCount vs toPass)
+- [ ] The fix stays local unless a shared helper truly owns the race
+- [ ] Local verification uses a targeted rerun
+- [ ] No behavioral changes to the test — only timing/retry strategy updated
+
+## Local Noise — Do Not Fix
+
+These are local distractions, not CI root causes:
+
+- Missing local input fixture files required by the test path
+- Missing local models directory
+- Teardown `EPERM` while restoring the local browser-test user data directory
+- Local screenshot baseline differences on Windows
+
+Rules:
+
+- First confirm whether it blocks the exact flaky path under investigation.
+- Do not commit temporary local assets used only for verification.
+- Do not commit local screenshot baselines.
