fix: record audio node not releasing microphone in Vue mode (#10829)

## Summary

Root cause: setting modelValue on recording completion triggers
NodeWidgets' updateHandler → widget.callback → litegraph recording
handler (getUserMedia), opening a second mic stream never cleaned up.

Fix:
- Stop writing to modelValue (keep defineModel to absorb parent v-model
without triggering the callback)
- On recording complete, set blob URL on litegraph audioUI DOM element
instead of uploading — let the original serializeValue (uploadAudio.ts)
handle upload at serialization time
- Remove registerWidgetSerialization to stop overriding litegraph's
serializeValue
- Move cleanup() before async onRecordingComplete in useAudioRecorder
- Dispose waveform AudioContext on stop

+# Browser Test Flake Prevention Rules
+
+Reference this file as `@browser_tests/FLAKE_PREVENTION_RULES.md` when
+debugging or updating flaky Playwright tests.
+
+These rules are distilled from the PR 10817 stabilization thread chain. They
+exist to make flaky-test triage faster and more repeatable.
+
+## Quick Checklist
+
+Before merging a flaky-test fix, confirm all of these are true:
+
+- 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
+- the fix stays local unless a shared helper truly owns the race
+- local verification uses a targeted rerun
+
+## 1. Start With CI Evidence
+
+- Do not trust the top-level GitHub check result alone.
+- Inspect the latest Playwright `report.json` directly, even on a green run.
+- Treat tests marked `flaky` in `report.json` as real work.
+- 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. Wait For The Real Readiness Boundary
+
+- Visible is not always ready.
+- If the behavior depends on internal state, wait on that state.
+- After canvas interactions, call `await comfyPage.nextFrame()` unless the
+  helper already guarantees a settled frame.
+- After workflow reloads or node-definition refreshes, wait for the reload to
+  finish before continuing.
+
+Common readiness boundaries:
+
+- `node.imgs` populated before opening image context menus
+- settings cleanup finished before asserting persisted state
+- locale-triggered workflow reload finished before selecting nodes
+- real builder UI ready, not transient helper metadata
+
+## 3. Choose The Smallest Correct Assertion
+
+- Use built-in retrying locator assertions when locator state is the behavior.
+- Use `expect.poll()` for a single async value.
+- Use `expect(async () => { ... }).toPass()` only when multiple assertions must
+  settle together.
+- Do not make immediate assertions after async UI mutations, settings writes,
+  clipboard writes, or graph updates.
+- Never use `waitForTimeout()` to hide a race.
+
+```ts
+await expect
+  .poll(() => comfyPage.settings.getSetting('Comfy.NodeLibrary.Bookmarks.V2'))
+  .toEqual([])
+```
+
+## 4. Prefer Behavioral Assertions
+
+- Use screenshots only when appearance is the behavior under test.
+- If a screenshot only indirectly proves behavior, replace it with a direct
+  assertion.
+- Prefer assertions on link counts, positions, visible menu items, persisted
+  settings, and node state.
+
+## 5. Keep Helper 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.
+
+## 6. Verify Narrowly
+
+- Prefer targeted reruns through `pnpm test:browser:local`.
+- On Windows, prefer `file:line` or whole-spec arguments over `--grep` when the
+  wrapper has quoting issues.
+- Use `--repeat-each 5` for targeted flake verification unless the failure needs
+  a different reproduction pattern.
+- Verify with the smallest command that exercises the flaky path.
+
+## Current Local Noise
+
+These are local distractions, not automatic 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 for handling local noise:
+
+- 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
