Sub-CA mode: Local CA loads CA cert+key from disk (CERTCTL_CA_CERT_PATH +
CERTCTL_CA_KEY_PATH) to operate as subordinate CA under enterprise root
(e.g., ADCS). Supports RSA, ECDSA, PKCS#8 keys. Validates IsCA and
KeyUsageCertSign. Falls back to self-signed when paths unset.
DNS-01 challenges: Pluggable DNSSolver interface with script-based hook
implementation. User-provided scripts create/cleanup _acme-challenge TXT
records for any DNS provider. Configurable propagation wait. Enables
wildcard certs and non-HTTP-accessible hosts.
step-ca connector: Smallstep private CA via native /sign API with JWK
provisioner auth. Issuance, renewal, revocation. Registered as iss-stepca.
23 new tests across 3 files. CI test path widened to ./internal/connector/issuer/...

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.
