Agents now report OS, architecture, IP address, hostname, and version
via heartbeat using runtime.GOOS, runtime.GOARCH, and net.Dial. New
migration adds columns to agents table. Heartbeat handler, service,
and repository updated to accept and persist metadata. GUI shows
OS/Arch in agent list and full system info in agent detail page.
Apache httpd connector: separate cert/chain/key files, apachectl
configtest validation, graceful reload. HAProxy connector: combined
PEM file (cert+chain+key), optional config validation, reload.
Both wired into agent binary's target connector switch.
14 tests for new connectors. All existing tests updated for new
Heartbeat/UpdateHeartbeat signatures. Docs updated across README,
architecture, concepts, and connectors guides.

- Exponential backoff on consecutive poll/heartbeat failures (max 5min)
- Panic recovery wrapper on agent.Run goroutine
- All 9 silent reportJobStatus errors now logged properly
- Key read failures return error and report job failure
- CommonName validation before CSR creation
- KeyDir permissions enforced with os.Chmod after MkdirAll
- splitPEMChain rewritten to use encoding/pem instead of string parsing

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
