Changelog

0.2.0 - 2026-07-25

Publish execution_plane as the common core-only substrate; JSON-RPC and process runtime ownership now lives exclusively in their component packages.
Add the admitted interactive runtime lifecycle contracts, bounded runtime errors and status/events, attach and input envelopes, and their boundary codecs.
Replace the former execute/stream runtime-client callbacks with the start/subscribe/input/status/cancel lifecycle.

Initial release.
