Jinwoo-HandOrca 4548d20cc4 fix(pty): patch node-pty native off-by-one leaking /dev/ptmx per spawn
node-pty 1.1.0's pty_posix_spawn on macOS walks low_fds[0..2] in an
allocation loop that breaks at the first fd >= STDERR_FILENO, then
cleans up via `for (; count > 0; count--) close(low_fds[count])`. In
the typical case (break at count=0) the cleanup body never runs and
low_fds[0] — a /dev/ptmx handle — leaks per spawn. Fixed upstream in
microsoft/node-pty af053f2 (PR #882), not in any 1.1.0 release.

Backport the 3-line cleanup-loop fix as a pnpm patch. E2E validated
against a dev daemon: 200 spawn/kill cycles kept the daemon's ptmx
fd count flat at baseline; prior runs reproduced linear 1-per-spawn
growth. Also documents the native root cause as a status addendum in
docs/fix-pty-fd-leak.md — the JS-side destroy() discipline previously
landed is still load-bearing for the SIGHUP-to-recycled-pid hazard and
for synchronous fd release on daemon shutdown.

Why The Folder Is Small

Earlier design and implementation work produced several planning and evaluation docs. Those were useful while the feature was taking shape, but they were intentionally removed once the implementation converged so future readers are not forced to choose between multiple overlapping sources of truth.
