JinjingandOrca f495b39a6a Fix untracked line-stat cache thrash and add source-control scale benchmark (#8022)
* Fix untracked line-stat cache thrash and add source-control scale benchmark (#8013)

The untracked line-stat cache capped at 2,048 entries while a git status
scan can carry up to DEFAULT_GIT_STATUS_LIMIT (10,000) untracked entries.
A sequential scan over more files than the cap FIFO-evicted every entry
before the next poll revisited it (~0% hit rate), so every 3s status poll
re-read every untracked file's full contents. Measured with 64KB files:
warm rescan cost per file was 17x higher just past the cap.

- Size the cache to 2x the status entry limit and make eviction LRU
  (delete-before-set on hit and refresh) so a hot worktree's entries
  survive another worktree's scan.
- Add tests/e2e/source-control-large-file-count.spec.ts: a 5-scenario
  Playwright benchmark (pnpm run test:e2e:source-control-scale) that
  reproduces #8013 deterministically — event-loop stall, DOM node count,
  JS heap, and OS-level renderer working set at 5k/9.5k/11k changed files,
  plus a clean-repo control and a cache-effectiveness gate. Scenarios
  asserting bounded row mounting go green with the SourceControl
  virtualization fix (#7619).
