So Many Crows v1: Sentry triage, crows, guardrails, trust ledger

Go command-line tool. Sentry classifies each todo item as solo, split,
or murder; text-only crows fly under budget, timeout, and flock caps;
trust is earned per crow and per task type; abusive requesters get a
mild, fading cooldown. Runs offline with a mock brain.
