feat: delay autostopping daemons when leaving directory

[jdx]

Summary

Implements GitHub discussion #103. Adds a configurable delay before autostopping daemons when leaving a directory, avoiding unnecessary restarts when briefly switching directories.

• Add PITCHFORK_AUTOSTOP_DELAY env var (default: 60 seconds)
• Set to 0 to disable delay and stop immediately (previous behavior)
• Track pending autostops in supervisor
• Cancel pending autostops when re-entering a directory

Test plan

• Set PITCHFORK_AUTOSTOP_DELAY=10 and verify autostop is delayed
• Leave and return to directory within delay, verify daemon keeps running
• Set PITCHFORK_AUTOSTOP_DELAY=0 and verify immediate stop behavior
• Leave directory and wait for full delay, verify daemon stops

Closes #103

Note

Introduces delayed autostop behavior controlled via PITCHFORK_AUTOSTOP_DELAY (default 60; 0 for immediate stop).

• Supervisor tracks pending autostops (pending_autostops) and schedules stops in leave_dir; processes due stops in process_pending_autostops during refresh
• Cancels pending autostops when re-entering a directory (cancel_pending_autostops_for_dir) and when starting a daemon (run clears pending)
• Adds E2E tests: delayed stop, cancel on return, and immediate stop with PITCHFORK_AUTOSTOP_DELAY=0
• Minor CLI help text tweaks for list and logs

Subdirectory navigation causes daemons to never autostop

Medium Severity

The cancel_pending_autostops_for_dir filter only checks if daemon_dir.starts_with(dir), which cancels autostops for daemons in the entered directory or its subdirectories. However, it doesn't check the reverse direction (dir.starts_with(daemon_dir)), so entering a subdirectory like /project/subdir won't cancel pending autostops for a daemon in /project. This causes the pending autostop entry to be removed later (without stopping the daemon due to the re-check), and when the user eventually leaves, the daemon is never re-scheduled for autostop because leave_dir also doesn't match parent directories.
