feat: attach video walkthrough of newly-added tests to PR comment (#14560)

<!-- ccr-slack-attribution -->
_Requested by **Christian Byrne** · [Slack
thread](https://comfy-organization.slack.com/archives/C090H3X4VBL/p1785633691296179?thread_ts=1785619438.875159&cid=C090H3X4VBL)_

## Summary

When a PR adds a **new** Playwright spec file, CI now records a video
walkthrough of just that new test and posts a link to it in the PR
comment, next to the existing trace-viewer link. The existing suite
keeps running without video, so CI cost/time doesn't grow.

## Changes

- **What**:
- `.github/workflows/ci-tests-e2e.yaml`: new
`playwright-video-new-tests` job diffs the PR against its base branch
(`git diff --diff-filter=A`) to find spec files added under
`browser_tests/tests/`. If (and only if) there are any, it re-runs just
those files with Playwright video recording turned on, then a new
`deploy-and-comment-video` job deploys the video(s) to Cloudflare Pages
(same mechanism as the existing trace/report deploy — `wrangler pages
deploy`) and extends the existing unified PR comment with a collapsed
`video` section, using the same `upsert-comment-section` action the
trace section already uses.
- `.github/workflows/ci-tests-e2e-forks.yaml`: mirrors the same
deploy+comment steps for forked PRs, following this repo's existing
fork-safe two-workflow split (`workflow_run` downloads the artifact and
posts the comment with write permissions, since fork PRs only get a
read-only token).
- `playwright.config.ts`: video is opt-in via a `RECORD_VIDEO=true` env
var (only set by the new CI job), slowed down via `SLOW_MO=1000` so the
recording is legible — no change to default behavior for local runs or
the rest of the suite.
- `scripts/cicd/extract-playwright-videos.ts` /
`scripts/cicd/pr-video-deploy-and-comment.sh`: new scripts mirroring the
existing `extract-playwright-counts.ts` /
`pr-playwright-deploy-and-comment.sh` pattern, but for video attachments
instead of trace/pass-fail counts.
- `browser_tests/fixtures/utils/litegraphUtils.ts`: fixes
`connectOutput`/`connectWidget` to route slot positions through
`toAbsolute()` before dragging (they were canvas-relative pixels being
fed to page-absolute drag coordinates).
  - `browser_tests/README.md`: documents the new-test video workflow.
- **Breaking**: none — additive only; existing trace/report comment
behavior is untouched, and the new jobs are not part of the required
`e2e-status` gate check.
- **Dependencies**: none new (reuses `wrangler`, already used by the
existing trace deploy step).

## Review Focus

- The "which files are new" detection (`git diff --diff-filter=A ...HEAD
-- browser_tests/tests`) relies on `fetch-depth: 0` in the new job's
checkout step.
- The bash `pr-*-deploy-and-comment.sh` scripts each duplicate their own
Cloudflare deploy-retry logic rather than sharing a helper — matching
the existing convention between `pr-playwright-deploy-and-comment.sh`
and `pr-storybook-deploy-and-comment.sh`, so this follows suit rather
than introducing a new shared-module pattern.

## Screenshots (if applicable)

N/A — this PR changes CI plumbing; the effect is a collapsible "🎬
New-test video walkthrough" section in a PR's bot comment whenever that
PR adds a new spec file.
