NeilandOrca 7f1e280436 Cut fseventsd load: fix macOS exclusion cap, drop wide always-on FSEvents streams (#7068)
* Cut fseventsd load: fix macOS exclusion cap, drop wide always-on FSEvents streams

- @parcel/watcher maps plain-path ignores to FSEventStreamSetExclusionPaths,
  but macOS caps exclusions at 8 per stream and fails closed. Orca passed 9,
  silently disabling ALL daemon-side exclusions: fseventsd delivered every
  node_modules/.git event to each per-worktree explorer stream (measured 16x
  client CPU). Cap plain paths at 8 (extras demoted to userspace globs) via a
  shared filesystem-watcher-ignore module, also unifying the runtime
  file-watcher host list so identical roots share one native stream.
- worktree-base-directory-watcher subscribed recursive FSEvents streams over
  every repo's ENTIRE workspace root (all worktrees) and whole common .git
  (objects included) with glob-only ignores (zero daemon-side exclusion),
  just to observe a few shallow paths. Replace with a 2s readdir/stat poller
  (zero fseventsd clients, measured 70x less delivery CPU); SSH targets keep
  provider.watch unchanged.
- serve-sim state watcher held an app-lifetime fs.watch on $TMPDIR (the
  noisiest dir on the system); its existing 250ms existence poll makes the
  parent watch redundant, so drop it.

* Eliminate base-poller idle cost: mtime-gated ticks + narrow macOS worktree-metadata stream

- base targets: tick is now one stat of each gate dir (root + nested
  containers); the readdir + marker fan-out runs only when a gate dir
  changed, with a 30s ungated backstop and a bounded pending-marker
  recheck list. Idle tick 600us -> 1.1us at 146 worktrees.
- git-common targets on macOS: replace the 2s entry sweep with one narrow
  native stream on <common>/.git/worktrees (tiny, rare-churn tree): zero
  idle syscalls and external worktree add/remove/HEAD detection back to
  sub-second. Re-arms via existence poll across git worktree prune
  deleting/recreating the dir. Win/Linux keep the listing poll (no
  fseventsd there; a Windows dir handle could block prune).
- split git-common logic into worktree-git-common-watch.ts (max-lines).
