feat(tui): add self-documenting help with ASCII diagrams and table helpers

TUI improvements for Christmas launch:
- Add phase transition table and lifecycle diagram to `gt molecule --help`
- Add swarm lifecycle diagram to `gt swarm --help`
- Add mail routing diagram to `gt mail --help`
- Add sling mechanics diagram to `gt sling --help`
- Create Lipgloss table helper (internal/style/table.go)
- Migrate mq_list to use styled tables with color-coded priorities
- Migrate molecule list to use styled tables
- Add fuzzy matching "did you mean" suggestions for polecat not found errors
- Add suggest package with Levenshtein distance implementation
