feat: Add tmux crash detection hooks (gt-i9s7o)
- Add SetPaneDiedHook to tmux package for crash detection - Add gt log crash subcommand for hook callback - Set pane-died hook when starting polecat sessions - Distinguish exit types: 0=done, 130=kill (Ctrl+C), other=crash - Rename townlog/townlog.go to townlog/logger.go 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
