* 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).
