chore: remove signal resource adapter package

Removes the Threadplane signal resource adapter package and private proof adapter from chat.

Drops the package from active docs generation, TypeScript path metadata, release groups, CI, publish, provenance, and lockfile metadata.

The remaining Threadplane surface is the runtime-neutral Agent contract; adapter ownership can move outside this repository.
