feat(037): capture, verification lifecycle, inheritance + close 036 stabilization

- Authoritative candidate capture with server-issued artifacts and raw-byte
  immutability hashing (source_response_hash server-owned)
- Closed-period lifecycle: request-hash bound approvals, persisted closure
  immutability violations, byte-for-byte catalog stability on reclosure
- Verification runs: persisted VerificationRun model + FK migration,
  publish gate (block_publish), scheduled observability runs (02:00 UTC)
- FR-013 baseline inheritance: prior_release_id migration, plan_inheritance/
  execute_inheritance classification and re-extraction, API endpoints
- Visual executor bound to release-deployment environment; caller mismatch
  rejected; visual SSIM/reconciliation modules
- Query execution decomposed: envelope/model/executor split, no direct SQL
- AgentRun approvals extracted to submodule; evidence adapter; _utils
- Dashboard testing service decomposed into 30+ modules (all <400 LOC)
- Five Feature-037 agent tools with permission guards (tools_037.py)
- API readiness endpoint; Alembic env/migrations; test fixture repos
- Specs 036/037 contracts, openapi.yaml, schema.json, tasks/traceability
  updated; semantic index rebuilt with 0 parse warnings
- Fix ADR-0003 parser ambiguity: remove [DEF🆔ADR] prose example
- Add axiom-mcp-agent-feedback.md: agent findings for MCP rework plan
- Tests: 298 service + 1464 API + 45 agent passing; ruff clean
