Add kaizen context resolver for scheduled agent fleet discovery.

Implement discover_kaizen_scheduled_repos and discover_kaizen_projects per
kaizen-agentic ADR-005 contract: State Hub roster, roster.yaml filter, schedule
validation, and prepare_command emission. Register kaizen/resolver/shell source
types with unit tests and runbook dry-run instructions.

 non-empty suggestion set with no duplicate target tasks on re-run.
 
+## Ops inventory evidence posture

+The current accepted live backend for activity-core ops inventory probes is
+State Hub progress with `event_type=ops_inventory_probe`.
+
+Inter-Hub / ops-hub per-entity submission remains intentionally deferred until
+all of these are true:
+
+- `OPS_HUB_KEY` is provisioned through an operator-owned secret path, never Git,
+  chat, or State Hub detail.
+- Widget or capability mapping is configured for the target ops-hub entities.
+- Production Inter-Hub intake is deployed and smoke-tested for the relevant
+  authenticated routes.
+
+Until then, missing Inter-Hub configuration should produce an explicit skipped
+sink result, not a failed probe. This posture was recorded in State Hub decision
+`7c235bbb-ee6f-4c3e-b1dd-74717eac9082`.
