Includes:
- Fix for incorrect type coercion / filtering inside `@optional` that
  didn't exist.
- Breaking changes to the representation of exposed Rust error types.
- Lots of small improvements to the quality of diagnostic messages for
  various kinds of incorrect queries.
- Maintenance release of trustfall_stubgen, to update to the new major
  Trustfall library dependency version.
