Merge branch 'main' into automation/ci-container-0.18.2

## Summary

Fix unhandled promise rejection ("Document is not focused") in Copy
Image and improve clipboard fallback reliability.

## Changes

- **What**: Two clipboard fixes:
1. `litegraphService.ts`: The "Copy Image" context menu passed async
`writeImage` as a callback to `canvas.toBlob()` without awaiting —
errors became unhandled promise rejections reported in [Sentry
CLOUD-FRONTEND-STAGING-AQ](https://comfy-org.sentry.io/issues/6948073569/).
Extracted `convertToPngBlob` helper that wraps `toBlob` in a proper
Promise so errors propagate to the existing outer try/catch and surface
as a user-facing toast instead of a silent Sentry error.
2. `useCopyToClipboard.ts`: Replaced `useClipboard({ legacy: true })`
with explicit modern→legacy fallback that checks
`document.execCommand('copy')` return value. VueUse's `legacyCopy` sets
`copied.value = true` regardless of whether `execCommand` succeeded,
causing false success toasts.

## Review Focus

- The `convertToPngBlob` helper does the same canvas→PNG work as the old
inline code but properly awaited
- The happy path (PNG clipboard write succeeds first try) is unchanged
- No public API surface changes — verified zero custom node dependencies
via ecosystem code search

+## CI Safety Rules
+
+**NEVER merge a backport PR without all CI checks passing.** This applies to both automation-created and manual cherry-pick PRs.
+
+- **Automation PRs:** The `pr-backport.yaml` workflow now enables `gh pr merge --auto --squash`, so clean PRs auto-merge once CI passes. Monitor with polling (`gh pr list --base TARGET_BRANCH --state open`). Do not intervene unless CI fails.
+- **Manual cherry-pick PRs:** After `gh pr create`, wait for CI before merging. Poll with `gh pr checks $PR --watch` or use a sleep+check loop. Only merge after all checks pass.
+- **CI failures:** DO NOT use `--admin` to bypass failing CI. Analyze the failure, present it to the user with possible causes (test backported without implementation, missing dependency, flaky test), and let the user decide the next step.

+
+### Never Admin-Merge Without CI
+
+In a previous bulk session, all 69 backport PRs were merged with `gh pr merge --squash --admin`, bypassing required CI checks. This shipped 3 test failures to a release branch. **Lesson: `--admin` skips all branch protection, including required status checks.** Only use `--admin` after confirming CI has passed (e.g., `gh pr checks $PR` shows all green), or rely on auto-merge (`--auto --squash`) which waits for CI by design.

+## CI Failure Triage
+
+When CI fails on a backport PR, present failures to the user using this template:
+
+```markdown
+### PR #XXXX — CI Failed
+
+- **Failing check:** test / lint / typecheck
+- **Error:** (summary of the failure message)
+- **Likely cause:** test backported without implementation / missing dependency / flaky test / snapshot mismatch
+- **Recommendation:** backport PR #YYYY first / skip this PR / rerun CI after fixing prerequisites
+```
+
+Common failure categories:
+
+| Category                    | Example                                  | Resolution                                |
+| --------------------------- | ---------------------------------------- | ----------------------------------------- |
+| Test without implementation | Test references function not on branch   | Backport the implementation PR first      |
+| Missing dependency          | Import from module not on branch         | Backport the dependency PR first, or skip |
+| Snapshot mismatch           | Screenshot test differs                  | Usually safe — update snapshots on branch |
+| Flaky test                  | Passes on retry                          | Re-run CI, merge if green on retry        |
+| Type error                  | Interface changed on main but not branch | May need manual adaptation                |
+
+**Never assume a failure is safe to skip.** Present all failures to the user with analysis.
