e744336385 fix: capability enforcement, credential safety, atomic delegations, input validation 
C-6: ConnectorRuntime enforces capability_mask per operation.
     READ-only ACs cannot invoke MUTATE operations (wipe, lock, retire).
C-7: AC validated against database (exists, active, not expired)
     before connector invocation.
C-9: Delegated AC capability bounded by delegator's capability.
C-10: Command counter uses atomic SQL increment with limit check.
M-23: expire_stale() uses same atomic SQL pattern.

H-1: Sensitive credential fields hidden from repr/logs via repr=False.
H-2: Stub backend requires ALLOW_STUB_CREDENTIALS=true to activate.
H-3: Kerberos backend raises CredentialResolutionError instead of
     returning stub ticket.
H-4: Chronicle INTENT emitted before execution, RESULT after.
H-5: device_id validated as UUID before Graph API URL interpolation.
H-8: ConnectorRuntime enforces governance for all connector invocations.

f7c49387c1 feat: absorb llm-principal-broker as gsap_broker/delegations/ 
Merges the standalone llm-principal-broker (1,132 LOC) into fastapi-gsap
as an in-process module. The previous architecture had two FastAPI
processes where the broker called GSAP over HTTP on every delegation
creation; now the lifecycle code uses GSAP's own async DB engine
directly and inserts AuthorizationContextDB rows in the same
transaction context.

New module: gsap_broker/delegations/
  models.py             Pydantic request/response shapes
  storage.py            DelegationDB SQLModel sharing the GSAP engine
  lifecycle.py          DelegationManager — in-process AC issuance via
                        AuthorizationContextDB.insert (no HTTP self-call)
  cleanup.py            30s background task for stale delegations
  router.py             /delegations/* FastAPI router (4 endpoints)
  registrars/
    base.py             AgentRegistrar Protocol + AgentCredentials
    stub.py             dev-mode no-op
    keycloak.py         Keycloak Admin REST API
    entra.py            Microsoft Entra Agent ID via Graph (lazy import)
    factory.py          driver selection (auto/stub/keycloak/entra)

Wiring:
  app.py mounts the delegations router and starts the cleanup task in
  the existing lifespan context manager.
  settings.py absorbs the keycloak_admin_*, entra_*, and
  agent_registrar fields from the old broker's settings.
  pyproject.toml adds an optional `entra` extra for the msal dep.

Behaviour preservation:
  - Endpoints kept identical: POST /, POST /{id}/revoke, GET /{id}, GET /
  - Chronicle event codes preserved: 0x3001 / 0x3003 / 0x3004
  - DelegationScope defaults unchanged (max_ttl_minutes=60, max_commands=500)
  - Capability ceiling -> capability_mask conversion documented inline

Smoke test: `python -c "from gsap_broker.app import app"` loads cleanly
with 26 routes including the four /delegations/ endpoints.

The standalone llm-principal-broker repo is archived to
~/projects/archive/llm-principal-broker.
