Pi Workflows 0.16.0

Highlights

• Unified the extension, CLI, and piw behind one versioned host client.
• Replaced the production piw SQLite reader with bounded host-owned views and content loading.
• Added robust cold-start, reconnect, retry, run-watch, and durable interaction recovery.
• Added piw <runId> --once for one complete plain-text workflow view.
• Added a packed-package end-to-end release gate that checks base Pi isolation, the workflow widget, pause and resume, worker parking, completion, and piw.

Reliability

• Bounded and materialized large live views through the host protocol.
• Kept complete views during retries and preserved explicit run selection.
• Improved missing-run, diagnostics, replay-state, and maintenance recovery.
• Added a real-model release check with exact provider and model validation and fallback rejection.

Packaging

• Added tsx as a production dependency because packaged TypeScript host and worker sources require it at runtime.
• Kept npm, crates.io, and Herdr plugin versions aligned at 0.16.0.
