Setup GBrain

Set up GBrain from scratch. Target: working brain in under 5 minutes.

Contract

• Setup completes with a working brain verified by gbrain doctor --json (all checks OK).
• The brain-first lookup protocol is injected into the project's AGENTS.md or equivalent.
• Live sync is configured and verified (a test change pushed and found via search).
• Schema state is tracked in ~/.gbrain/update-state.json so future upgrades know what the user adopted or declined.
• No Supabase anon key is requested; GBrain uses only the database connection string.

Install (if not already installed)

bun add github:garrytan/gbrain
