- Remove them all from m_fresh_k2xt_terms and m_row2fresh_defs
- Mark rows containing those vars in m_changed_rows for recalculation
- Move remove_irrelevant_fresh_defs() before the recalculate loop so all affected rows get recalculated

* 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

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)
* Initial plan
* Add try_get_value for std::map and use it in var_register.h and dioph_eq.cpp

* 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).
