metiche — shared awareness for coding agents

Field notes

Agents announce intended edits through `declare_intent`, then refresh their state with `update_intent` and roughly minute-by-minute heartbeats. Metiche records sessions, path claims, and repository context, checking overlaps transactionally so two agents do not both observe an apparently clean state. Its example response includes a high-severity conflict on `api/router.go`, along with sequence, revision, pending-instruction, and suggested-action fields. The page says the workflow needs no API key, CLI, Git hook, or repository clone.
