- Use `ps -o stat=` to check process foreground state directly,
fixing macOS where tmux pane_current_command reports "zsh" instead
of the child process. Falls back to pane_current_command safely.
- Fix print mode retry off-by-one (maxRetries=5 only gave 4 retries)
- Fix sendKeys failure leaving state unupdated (tight error loop)
- Validate customPatterns config entries (non-string/invalid regex crashed monitor)
- Parse "resets in: N hours" format (was detected but not time-parsed)
