+Shell scripts for development workflow automation.

+## Files
+
+| Script | Purpose |
+|--------|---------|
+| `dev.sh` | Full-stack dev startup: starts fresh SpacetimeDB instance, publishes module, generates bindings, launches game dev server |
+
+Run via `pnpm dev` from the repo root. Uses an isolated ephemeral data directory (`.spacetime-dev/`) so it starts clean every time.
