* Update Z3_mk_datatype_sort API to accept array of sort parameters and add Z3_mk_polymorphic_datatype (#7966)

* Initial plan

* Update Z3_mk_datatype_sort API to accept array of parameters

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Update language bindings for parametric datatype sort API

- Python: Updated DatatypeSort() to accept optional params list
- OCaml: Added mk_sort_ref_p/mk_sort_ref_ps for parametric datatypes
- .NET: Added MkDatatypeSortRef() methods with optional params
- Java: Added mkDatatypeSortRef() methods with optional params
- All changes maintain backward compatibility

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Fix .NET build error - rename params to parameters

The 'params' keyword is reserved in C#, causing compilation errors.
Renamed parameter from 'params' to 'parameters' in MkDatatypeSortRef methods.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add unit test for parametric datatypes

Added test_parametric_datatype.cpp to demonstrate polymorphic datatypes.
The test creates two concrete instantiations of a generic pair concept:
- pair_int_real with fields (first:Int, second:Real)
- pair_real_int with fields (first:Real, second:Int)
Then verifies that accessors work correctly and type checking is enforced.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Implement polymorphic type variables support for parametric datatypes

- Modified datatype_decl_plugin to allow type variables as parameters
- Updated mk_datatype_decl to extract type variables from field sorts
- Type variables are collected in order of first appearance
- Revised unit test to use Z3_mk_type_variable for polymorphic datatypes
- Test creates pair datatype with type variables alpha and beta
- Successfully instantiates with concrete types (pair Int Real) and (pair Real Int)
- Verifies accessor types match and equality terms are well-typed
- All tests pass

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add Z3_mk_polymorphic_datatype API and refactor datatype creation

- Added new API Z3_mk_polymorphic_datatype to z3_api.h
- Renamed static mk_datatype_decl to api_datatype_decl in api_datatype.cpp
- Modified api_datatype_decl to accept explicit type parameters
- Updated all callers to use renamed function
- Added test_polymorphic_datatype_api demonstrating new API usage
- Both tests pass successfully

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Remove type variable collection logic from constructors

Removed the logic for collecting type variables from field sorts based on constructors.

* Update comments on parameter handling in api_datatype.cpp

Clarify usage of parameters in API documentation.

* Fix OCaml build error - use list instead of array for mk_datatype_sort

Changed mk_sort_ref to pass empty list [] instead of empty array [||].
Changed mk_sort_ref_p to pass params list directly instead of converting to array.
Z3native.mk_datatype_sort expects a list, not an array.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add polymorphic datatype example to C++ examples

Added polymorphic_datatype_example() demonstrating:
- Creating type variables alpha and beta with Z3_mk_type_variable
- Defining parametric Pair datatype with fields of type alpha and beta
- Instantiating with concrete types (Pair Int Real) and (Pair Real Int)
- Getting constructors and accessors from instantiated datatypes
- Creating constants and expressions using the polymorphic types
- Verifying type correctness with equality (= (first p1) (second p2))

* add the  "noexcept" keyword to value_score=(value_score&&) declaration

* expose a status flag for clauses but every single one is being coded as an assumption...

* Add a fast-path to _coerce_exprs. (#7995)

When the inputs are already the same sort, we can skip most of the
coercion logic and just return.

Currently, `_coerce_exprs` is by far the most expensive part of
building up many common Z3 ASTs, so this fast-path is a substantial
speedup for many use-cases.

* Bump actions/setup-node from 5 to 6 (#7994)

f544dd4ab2 deal with warnings
@levnach - there are some additional warnings.
You could revert the change to std_vector or use usize() that I added to vector.h. Look at build logs from the pipelines or actions or figure out how to add a continuous AI script to fixup build warnings (I tried a few times earlier on but the features available to do this were not for laymen).

Centralize and document TRACE tags using X-macros (#7657)
* Introduce X-macro-based trace tag definition
- Created trace_tags.def to centralize TRACE tag definitions
- Each tag includes a symbolic name and description
- Set up enum class TraceTag for type-safe usage in TRACE macros

* Add script to generate Markdown documentation from trace_tags.def
- Python script parses trace_tags.def and outputs trace_tags.md

* Refactor TRACE_NEW to prepend TraceTag and pass enum to is_trace_enabled

* trace: improve trace tag handling system with hierarchical tagging

- Introduce hierarchical tag-class structure: enabling a tag class activates all child tags
- Unify TRACE, STRACE, SCTRACE, and CTRACE under enum TraceTag
- Implement initial version of trace_tag.def using X(tag, tag_class, description)
  (class names and descriptions to be refined in a future update)

* trace: replace all string-based TRACE tags with enum TraceTag
- Migrated all TRACE, STRACE, SCTRACE, and CTRACE macros to use enum TraceTag values instead of raw string literals

* trace : add cstring header

* trace : Add Markdown documentation generation from trace_tags.def via mk_api_doc.py

* trace : rename macro parameter 'class' to 'tag_class' and remove Unicode comment in trace_tags.h.

* trace : Add TODO comment for future implementation of tag_class activation

* trace : Disable code related to tag_class until implementation is ready (#7663).
