feat: auto-load .env files, remove VS Code boot throttle

Add dotenv.go — loads .env from cwd and ~/.codebase/.env on startup
so users can drop a config file next to the binary instead of
setting environment variables manually. Real env vars always win.

Remove VS Code/Cursor boot animation throttle (8fps → 20fps) and
re-enable logo glow effect in all terminals.
