This release includes various breaking refactors and improvements:
- A lot of work has been done towards linking Hugrs. Now module-rooted
Hugrs can
  be linked together using configurable policies.
- `ValueArray` has been removed.
- A type-safe API for accessing metadata on nodes has been added.
- Envelopes now have an extensive API for progressively describing a
package,
  and failing gracefully on errors.
- The MSRV has been bumped to Rust 1.89, and the public pyo3 dependency
has been
  updated to 0.27.
- Multiple deprecated definitions have been removed.
