Brennan Benson f8b9c2984d fix(watcher): host macOS git-common narrow watch in the watcher child (#9091)
* fix(watcher): host macOS git-common narrow watch in the watcher child

The darwin-only .git/worktrees narrow stream was the last production
path loading @parcel/watcher's native module inside the Electron main
process. watcher.node 2.5.6 has unsynchronized cross-thread access to
watcher state during unsubscribe/root-deletion (FSEventsBackend.cc:60/
64 vs :336, :250 vs :262, and the deletedRoot double-stopStream) that
corrupts the hosting process heap; `git worktree prune` deleting an
empty worktrees dir makes that overlap routine, and the resulting
PartitionAlloc trap killed the whole app (issue #8732, EXC_BREAKPOINT
on the FSEvents thread in Watcher::isIgnored).

Route the subscription through the existing crash-isolated watcher
child supervisor instead, matching every other native watch (#7547).
Error and root-deletion teardown/re-arm semantics are unchanged; a
watcher-child interruption now reports a structural change so the
worktree list re-syncs across the resubscribe gap.

Fixes #8732
