02142f7be4 feat: Entra Agent ID auth provider + governance leak cleanup 
New crate: bascule-auth-agent-id
  Microsoft Entra Agent ID authentication for AI agents
  Validates OAuth tokens against Entra JWKS (60min cache)
  Extracts agent metadata: type, blueprint, sponsor, scopes
  Detects on-behalf-of (delegated) agents
  Token-as-password pattern for SSH auth

Cleanup:
  Removed all governance-specific references from comments
  SessionHandler trait is the only extension point
  Zero substrate/chronicle/gsap dependencies
  Config example uses neutral terminology

Config:
  [auth.agent_id] section for Entra configuration
  tenant_id, audiences, multi_tenant fields

3 crates: bascule-core, bascule-server, bascule-auth-agent-id

bfa26cfd15 feat: Bascule — identity-aware SSH proxy 
Open-source SSH proxy with pluggable authentication and
extensible session handling. Zero external governance dependencies.

Core (bascule-core):
  russh 0.46 SSH server with PTY bridge (portable-pty)
  Pluggable auth: AuthProvider trait (SSH keys, accept-all dev mode)
  SessionHandler trait for extending behavior (audit, governance)
  TOML configuration, ephemeral Ed25519 host key generation

Binary (bascule-server):
  Single binary, 5.6MB release build
  CLI with --config flag
  Default: accept-all auth on port 2222

Extension points:
  AuthProvider — implement for OIDC, certificates, custom auth
  SessionHandler — implement for audit, governance, recording
  DefaultHandler — passthrough (ships with open-source version)

Zero substrate/chronicle/gsap/hfl dependencies.
