v0.5.0

Added

• Inngest adapter (inngest): emits a TypeScript Inngest app that
  mounts into an existing Node/Next.js service, with waitForEvent
  HITL gates.
• Raw Python adapter (python): a maximum-legibility,
  orchestrator-free plain-script target; refuses hitl_gate pipelines
  at emit time.
• DBOS trigger backend for rote serve, so the default runtime can be
  MCP-triggered.
