Tyler King f3ffeb38ae feat: AgentRegistrar abstraction + Entra Agent ID driver
Extracts agent identity registration behind AgentRegistrar protocol.
Three implementations:
  KeycloakRegistrar — Keycloak Admin REST API (existing, refactored)
  EntraRegistrar    — Microsoft Entra Agent ID platform (NEW)
  StubRegistrar     — dev mode without real IdP

Driver selection via AGENT_REGISTRAR env var:
  auto     — prefers Entra if configured, Keycloak fallback, stub default
  keycloak — explicit Keycloak
  entra    — explicit Entra Agent ID

Entra integration:
  Registers agent as Entra app + service principal via Graph API
  Tags with delegation metadata (agent_type, delegator, governed:true)
  Client secret TTL matches delegation expiry
  Deletes application on revocation (cascades to SP)
  Uses msal for token acquisition
  Future: native Agent ID Blueprint API when GA

Files:
  registrar.py         — AgentRegistrar protocol + AgentCredentials dataclass
  registrar_keycloak.py — refactored from keycloak.py
  registrar_entra.py   — NEW Entra Graph API driver
  registrar_stub.py    — dev mode stub
  registrar_factory.py — driver selection factory
  delegation.py        — updated to use registrar abstraction
  settings.py          — added Entra config + agent_registrar field

All 7 smoke tests pass with stub registrar.
Implements GCAP-SPEC-LLM-PRINCIPAL-BROKER-0001 §4.1-§4.3.
