9d9ad6588e Phase D: Automated DNS registration via MCNS 
Add DNSRegistrar that creates/updates/deletes A records in MCNS
during deploy and stop. When a service has routes, the agent ensures
an A record exists in the configured zone pointing to the node's
address. On stop, the record is removed.

- Add MCNSConfig to agent config (server_url, ca_cert, token_path,
  zone, node_addr) with defaults and env overrides
- Add DNSRegistrar (internal/agent/dns.go): REST client for MCNS
  record CRUD, nil-receiver safe
- Wire into deploy flow (EnsureRecord after route registration)
- Wire into stop flow (RemoveRecord before container stop)
- 7 new tests, make all passes with 0 issues

c7e1232f98 Phase C: Automated TLS cert provisioning for L7 routes 
Add CertProvisioner that requests TLS certificates from Metacrypt's CA
API during deploy. When a service has L7 routes, the agent checks for
an existing cert, re-issues if missing or within 30 days of expiry,
and writes chain+key to mc-proxy's cert directory before registering
routes.

- Add MetacryptConfig to agent config (server_url, ca_cert, mount,
  issuer, token_path) with defaults and env overrides
- Add CertProvisioner (internal/agent/certs.go): REST client for
  Metacrypt IssueCert, atomic file writes, cert expiry checking
- Wire into Agent struct and deploy flow (before route registration)
- Add hasL7Routes/l7Hostnames helpers in deploy.go
- Fix pre-existing lint issues: unreachable code in portalloc.go,
  gofmt in servicedef.go, gosec suppressions, golangci v2 config
- Update vendored mc-proxy to fix protobuf init panic
- 10 new tests, make all passes with 0 issues

15b8823810 P1.2-P1.5: Complete Phase 1 core libraries 
Four packages built in parallel:

- P1.2 runtime: Container runtime abstraction with podman implementation.
  Interface (Pull/Run/Stop/Remove/Inspect/List), ContainerSpec/ContainerInfo
  types, CLI arg building, version extraction from image tags. 2 tests.

- P1.3 servicedef: TOML service definition file parsing. Load/Write/LoadAll,
  validation (required fields, unique component names), proto conversion.
  5 tests.

- P1.4 config: CLI and agent config loading from TOML. Duration type for
  time fields, env var overrides (MCP_*/MCP_AGENT_*), required field
  validation, sensible defaults. 7 tests.

- P1.5 auth: MCIAS integration. Token validator with 30s SHA-256 cache,
  gRPC unary interceptor (admin role enforcement, audit logging),
  Login/LoadToken/SaveToken for CLI. 9 tests.

All packages pass build, vet, lint, and test.
