* fix(source-control): stop measuring layout on every virtual list render
Shared-scroller scrollMargin used a deps-less useLayoutEffect that called
getBoundingClientRect after every React render (including git-status polls).
Measure on mount/attach only, then refresh via ResizeObserver and childList
MutationObserver with cleanup, and add focused tests for no render-time
layout reads plus multi-section margin updates.
* fix(source-control): prune stale layout observers
* 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).
