chore: sync codebase remediation, gameplay systems, and docs

Security & infrastructure:
- Remove unused services/ (auth, spacetimedb) and auth.db
- Add .env.example template, expand .gitignore for env/db files
- Add GitHub Actions CI + commitlint config and workflows
- Add manual vendor chunking and source maps to docs/site vite configs

Shared UI & docs app:
- Add ARIA props and focus-visible rings to Button/Panel
- Add ButtonAsLink primitive; use shared Button in NotFound
- Wire @void-nav/ui into docs app; refresh content pages
- Replace Todo page with Kanban board

Gameplay (Bevy):
- Add ai module (behavior, faction, navigation, perception, spawning, states)
- Add narrative module (events, history, synthesis, ui)
- Refine galaxy contents and in-system flight/scene systems
