Closes #2287 .

Testing:

  • All existing hugr-py tests that call validate() perform a round-trip, checking that the hashes of the start and end Hugrs (computed using the _NodeHash method defined in conftest.py) agree.
  • I exported all the Hugrs generated by tests in the guppylang repo (using just export-integration-tests) and tried importing them (1) using the old method via json and (2) using the new method, and checked that the hashes of the two imported Hugrs agree (using the same _NodeHash method).

There are a few TODO comments remaining in load.py which I could not see a way to resolve using the existing model. I will investigate these further and raise issues if necessary.

shouldn't this be a breaking change?

I think this doesn't count as a breaking change since the hugr._hugr module is underscored.

I had no idea these definitions leaked outside the match block 🤯
I'd prefer if this logic was inside the first case branch anyway

In two minds, but on balance I prefer this way, the advantage being much smaller match blocks and less indentation.

After all the hugrs are imported I think this should be unset. Maybe it could be an explicit enter/exit paradigm like with enter_symbol instead of a field?

Hmm, actually ... this is true in the hugr graph, and it does appear to be true in the model as well ... but I'm not sure that it's guaranteed in the latter. So prefer to leave like this just in case.

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.
