Gamspy

------------
- General
- Improve the performance of frozen solves.
- Add support for new equation, variable matching syntax for MCP models.
- Ignore empty and newlines in the existing solvers file.
- Use finalizers instead of __del__.
- Cache solver capabilities, default solvers and installed solvers to speed up solver validation.

- Perform pip audit check in the pipeline instead of pre-commit.
- Upgrade gamspy_base and gamsapi dependencies.
- Documentation

------------
- General

- Introduce `name_prefix` option to NN formulations for ease of debugging.
- Documentation
- Add a section in FAQ about the compatibiltiy issues of the Python interpreter from the Microsoft Store.
- Fix minor issue in embedding Neural Network documentation.
- Testing
- Enforce the order of tests. Run unit tests first, and model library tests last.
- Use spawn method for multiprocessing to avoid possible deadlocks with fork method.

------------
- General
- Upgrade pre-commit dependencies.
- Enhance bound propagation for `AvgPool2d` class.
- Allow adding debug options to Options objects.

- Allow dumping gams state on `.toGams` call.
- Allow indexing into symbols with integers.
- Add `bypass_solver`, `cutoff`, and `default_point` options.
- Replace conda, pip and virtualenv with uv in ci pipelines.
- Add --use-uv option to allow solver downloads with uv.
- Provide ssl context explicitly for NEOS backend.
- Add configurable options via set_options and get_option.
- Fix bug in an edge case of the vector-matrix multiplication.
- Testing
- Add an lp and a qcp benchmark for performance comparison.
- Documentation

------------
- General
- Fix the bugs in dynamic set assignments.
- Rewrite parts of GAMS Control API.
- Fix debugging level bug of NEOS backend.
- Fix license issue of big models that are solved with frozen solve.
- Allow loadRecordsFromGdx to domain forward.

- Documentation
- Update embedding Neural Network documentation.

------------
- General
- Fix implicit parameter validation bug.
