fix: reap orphaned browser sessions on startup (#7931)
When a Python process exits uncleanly (SIGKILL, crash, gateway restart
via hermes update), in-memory _active_sessions tracking is lost but the
agent-browser node daemons and their Chromium child processes keep
running indefinitely. On a long-running system this causes unbounded
memory growth — 24 orphaned sessions consumed 7.6 GB on a production
machine over 9 days.

Add _reap_orphaned_browser_sessions() which scans the tmp directory for
agent-browser-{h_*,cdp_*} socket dirs on cleanup thread startup.  For
each dir not tracked by the current process, reads the daemon PID file
and sends SIGTERM if the daemon is still alive.  Handles edge cases:
dead PIDs, corrupt PID files, permission errors, foreign processes.

The reaper runs once on thread startup (not every 30s) to avoid races
with sessions being actively created by concurrent agents.
