fix: robust terminal focus with session targeting and code review fixes

- Extract helpers: focusTerminalTab, getTtyViaPsForPids, escapeAppleScript
- Batch ps tty lookup (single call for all PIDs instead of sequential)
- Target specific session tty when g pressed on session row
- Sort ttys by most recent activity for project-level focus
- Deduplicate tried ttys between primary and fallback paths
- Escape AppleScript interpolations to prevent injection
- Wrap flash animation in try/end try for mid-close safety
- Wrap async handleKeypress in try/catch for unhandled rejections
- Fix activeTag padding for consistent column alignment
