feat(capabilities): metadata, frozen registry, scoped grants and requests
- Capabilities declare access (read/write, unknown fails closed as write), side effects, idempotency, timeout, cost estimate and the trust of their output (web content is low trust). A capability may derive its policy target from its parameters; a disagreeing target is refused, and approvals whose modified parameters change the target are refused. - The registry is frozen at start-up; registration afterwards panics. - Invocation.RequireApproval turns ALLOW into ASK for commitments; it can only tighten, and scoped grants never satisfy it. - Scoped grants (migration 0025): capability, target and parameter globs, access, expiry of at most seven days and an optional operation count consumed atomically; applied only where policy says ASK. A sweep marks lapsed grants and refreshes the self-model, which now lists live grants. - Capability requests carry scope, duration, operation cap, reason, evidence, risk, mitigation, fallback, alternatives and explicit decision history; they batch per intention, are capped per mind (operator attention budget) and can be decided only by a named person. Component names are refused as deciders, for approvals too, and as usernames. - API routes, OpenAPI entries, scheduler sweeps and approval-centre sections for requests and temporary grants.
