Fix implicit conversion warnings: use UINT_MAX instead of -1 for unsi… (#8342) 
* Fix implicit conversion warnings: use UINT_MAX instead of -1 for unsigned variables

Replace implicit conversion from negative literal to unsigned type
with explicit UINT_MAX constant to eliminate compiler warnings.

Fixed 10 instances across 6 files:
- src/ast/rewriter/bv_rewriter.cpp: 1 instance
- src/ast/sls/sls_bv_tracker.h: 2 instances
- src/math/lp/dioph_eq.cpp: 3 instances
- src/math/lp/lp_primal_core_solver.h: 2 instances
- src/muz/transforms/dl_mk_array_instantiation.cpp: 1 instance
- src/muz/transforms/dl_mk_synchronize.cpp: 1 instance

These changes preserve the exact same runtime behavior (UINT_MAX
equals the wrapped value of -1 for unsigned types) while making
the code more explicit and warning-free.

* Update bv_rewriter.cpp

b154667092 Fix memory leak in undo_fixed_column for big numbers 
The undo_fixed_column struct is region-allocated via trail_stack, so its
destructor is never called. When m_fixed_val contains a big number (one
that doesn't fit in a small int), the heap-allocated memory for the mpq
numerator/denominator was never freed.

Fix by calling m_fixed_val.reset() in undo() to explicitly free the
heap memory before the region deallocates the struct.

Verified with macOS leaks tool:
- Before: 126 leaks (6048 bytes) on convert-jpg2gif-query-1584.smt2
- After: 0 leaks on normal completion, 10 leaks on timeout (unfinished trail)

* Fix memory corruption in Z3_polynomial_subresultants

The API function had a memory corruption bug where allocating the result
vector while the default_expr2polynomial converter was still in scope
could corrupt the converter's internal expr2var mapping.

Fixed by restructuring the code to:
1. Complete all polynomial computation in a scoped block
2. Store results in a temporary expr_ref_vector
3. Let the converter go out of scope
4. Then allocate and populate the result vector

Also improved the test to:
- Use randomized testing with 20 iterations
- Test both cases: variable in polynomials and variable not in polynomials
- Use proper reference counting (inc_ref before dec_ref)

Refactor mk_and and mk_app to use std::span API (#8285) 
* Initial plan

* Refactor mk_and and mk_app to use std::span

- Made mk_and(unsigned num_args, expr * const * args) private
- Added new public mk_and(std::span<expr* const> args) method
- Added new public mk_app(family_id fid, decl_kind k, std::span<expr* const> args) method
- Updated all convenience overloads to use std::span version
- Updated all external call sites to use the new std::span API

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

* Fix remaining test files to use std::span API

- Updated src/test/sorting_network.cpp
- Updated src/test/ho_matcher.cpp with explicit cast to resolve ambiguity

* Revert overlapping changes superseded by PR #8286

Reverted 30 files to match the state from PR #8286 (commit ebc0688) which refactored mk_and/mk_or call sites to use vector overloads. This supersedes the std::span changes in those files.

Retained std::span changes in files unique to this PR:
- Core API changes (ast.h, ast.cpp)
- Files not affected by PR #8286 (api_context.cpp, ast_util.cpp, bool_rewriter.h, datatype_rewriter.cpp, dom_simplifier.cpp, factor_rewriter.cpp, pb2bv_rewriter.cpp, quant_hoist.cpp, spacer_cluster_util.cpp, sortmax.cpp, array_axioms.cpp, smtfd_solver.cpp, goal.cpp, ho_matcher.cpp, qe_arith.cpp, sorting_network.cpp)
- Special case in hnf.cpp where both PRs modified different lines
