* fix(cli): unwedge cua-driver installer timeouts — group-kill on timeout, stale-lock pre-clear, 660s ceiling
The cua-driver refresh in hermes update could wedge permanently:
subprocess timeout (300s) killed only the outer shell, orphaning the
curl|bash grandchildren and the upstream installer's concurrent-install
lock (~/.cua-driver/packages/.install.lock.d). The installer only
reclaims a stale lock after 600s of waiting — longer than our old
ceiling — so every subsequent run was killed before recovery could
fire: 'always times out'.
- Run the installer in its own process group (start_new_session) and
SIGKILL the whole group on timeout, so no lock-holding orphans survive.
- Pre-clear a provably-stale lock (dead holder pid, or pid-less and
older than the upstream 600s window) before invoking the installer.
- Raise the ceiling to 660s (> upstream LOCK_STALE_AFTER_SECONDS=600).
- Timeout message now names the lock path and the manual re-run command.

* chore: suppress windows-footgun lint on platform-gated kill calls
Both sites are POSIX-only: _clear_stale_cua_install_lock early-returns
on win32, and os.killpg sits in the 'not is_windows' branch.
