feat(server): W2-D agent assembly, session API, runAgent/resolveDecision and backend e2e

- Capabilities: all 14 registered (AO: inventory.query, download.plan/submit, organize.plan/execute,
  policy.preview/apply; agent: task.inspect/retry/cancel); startup asserts count == 14.
  Registry injects server-side authorize (automation_grant by action/scope/policy version/budget,
  one-shot approval bound to plan id + payload hash + revision + expiry; model claims ignored;
  automation switch), audit_event, server idempotency keys and a capability_invocation op ledger
  (migration 0021) used for crash reconciliation. download.plan creates draft plans only;
  download.submit promotes draft -> reserved after authorization.
- Agent session API: POST/GET /agent/runs, GET /agent/runs/{id} (events by seq, messages, report),
  POST .../messages (wake), POST .../abort; automation-grants, approvals, capabilities invoke, tasks.
- runAgent task: Pi or fake provider from settings (apiKey via secrets), events persisted to
  agent_run_event then published, resume + ledger reconciliation when pendingOperations > 0,
  waits for goal-linked downloads/imports and reports from business tables (submitted != imported).
- Background triggers: decision.created -> bounded plan_only investigation (dedupe per decision);
  decision.updated(resolved) -> resolveDecision executes chosen option.
- W2 closure: all OpenAPI routes registered in contracts api.ts (+ subset test); TMDB key from
  settings secret_ref with env fallback; PUT /sites/{id}/credentials documented as alias of
  /site-accounts; completion events documented as existing status events.
- e2e (real PG + OpenWorkflow + testkit mocks): RSS->library, agent delegation with grant/deny,
  background continuation, worker kill -9 recovery (single qB add), auto investigation dedupe.
