Setup GBrain

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

Installing into an agent harness? (Claude Code, Codex, OpenClaw, etc.) gbrain bootstrap is the paste-in install path — it wires hooks, the maintenance sweep, and harness config in one command. On a box that already hosts a brain + a running gbrain serve --http (agent-framework boxes), gbrain bootstrap harness --yes wires framework-spawned Claude Code/Codex sessions instead — no agent workspace needed. See https://github.com/garrytan/gbrain/blob/master/docs/guides/bootstrap.md. This skill covers the brain-side setup (database, sync, first import); the two are complementary.
