Add game UI panels, keyboard shortcuts, docs narrative overhaul, and unified dev script

- Add MiniStarMap, NpcMarketPanel, ShipStatusPanel, useKeyboardShortcuts
- Add progress bars for approach/mining operations and cargo fill indicator
- Rewrite docs from spreadsheet-first to exploration-first open-world RPG
- Replace dev:db + dev:standalone with unified dev script (scripts/dev.sh)
- Add Vite chunk splitting for three.js and spacetimedb
- Fix displayName dependency in useSpacetimeConnection
- Remove stale usePlayerSession.ts
- Add AGENTS.md files across all packages

+# apps/docs — Living Design Documentation
+
+Package: `@void-nav/docs`
+Port: `http://localhost:5173/docs`
+
+This is the **design documentation hub** and interactive prototype playground. It contains the full GDD as 16 browsable pages, 14 interactive demos validating individual game subsystems, and a complete game-slice prototype implementing the full MVP loop in-browser with localStorage.
+
+## Structure

+
+## Key Design Decisions
+
+- Docs are **React components**, not markdown files — this allows interactive demos inline with documentation
+- The `game-slice/` prototype is a self-contained playable game that validates the full loop before backend migration
+- All 14 demos in `existing-demos/` use the R3F scenes in `r3f/`
