bymyself e36a5cd1fc feat: add V8 code coverage collection for Playwright E2E tests
Adds infrastructure to collect V8 JavaScript code coverage during Playwright
E2E test runs and generate lcov/html reports.

Architecture:
- Custom page fixture in ComfyPage.ts starts V8 JS coverage before each test
  and stops it after, fetching source text for network-loaded scripts
- @bgotink/playwright-coverage reporter (v0.3.2) processes V8 coverage data
  into Istanbul format, generating lcov and text-summary reports
- pnpm patch on the reporter fixes two issues:
  1. Adds filesystem fallback for sourcemap loading — when HTTP fetch fails
     in the worker thread, reads .map files from dist/ on disk
  2. Rewrites Vite sourcemap source paths from build-output-relative
     (../../src/foo.ts) to project-relative (src/foo.ts) so they aren't
     excluded by the library's path validation

CI workflow (ci-tests-e2e-coverage.yaml):
- Runs on PRs and pushes to main/core/*
- 60-minute timeout, 2 workers, chromium project
- Uploads coverage/playwright/ as artifact for downstream reporting

Results: 96.1% line coverage, 68.1% branch coverage, 60.9% function coverage
across 1,221 source files.
