v0.3.0

Added

• Cloudflare Workflows adapter (cloudflare) — the second runtime,
  proving the IR is runtime-agnostic — and the DBOS adapter.
• rote serve / rote register: expose compiled pipelines as MCP
  tools (FastMCP 3.x, stdio + Streamable HTTP).
• Data-flow threading: nodes declare inputs: and adapters thread real
  payloads through the DAG.
• rote shipped as a Claude Code plugin.

Changed

• Distribution renamed to rote-cli on PyPI (import and CLI stay
  rote); package made release-ready with tag-driven Trusted
  Publishing.
