Private keys never leave agent infrastructure. Agents generate ECDSA P-256
key pairs locally, store them with 0600 permissions, and submit only the CSR
(public key) to the control plane. New AwaitingCSR job state pauses
renewal/issuance jobs until the agent submits its CSR. Server-side keygen
retained behind CERTCTL_KEYGEN_MODE=server for demo/development.
Key changes:
- Dual keygen mode via CERTCTL_KEYGEN_MODE (agent default, server for demo)
- AwaitingCSR job state with CommonName/SANs in work response
- Agent ECDSA P-256 keygen, local key storage, CSR-only submission
- CompleteAgentCSRRenewal server-side flow for agent-submitted CSRs
- DeploymentRequest.KeyPEM for agent-provided keys during deployment
- Dockerfile.agent creates /var/lib/certctl/keys with correct ownership

Service layer (63 tests): certificate, agent, audit, job, notification,
policy, and renewal services with mock repositories covering threshold
alerting, deduplication, status transitions, and job processing.
Handler layer (46 tests): certificate and agent HTTP handlers using
httptest with mock service interfaces, covering success/error paths,
pagination, JSON marshaling, and path parameter extraction.
Integration (11 subtests): end-to-end certificate lifecycle test
exercising real services and Local CA issuer through HTTP API —
create cert, trigger renewal, process jobs, register agent, heartbeat,
verify audit trail.
