* somewhaat failed attempt at declaring subterm predicate
I can't really figure out how to link the smt parser to the rest of the
machinenery, so I will stop here and try from the other side. I'll start
implmenting the logic and see if it brings me back to the parser.
* initial logic implmentation
Very primitive, but I don't like have that much work uncommitted.
* parser implementation
* more theory
* Working base
* subterm reflexivity
* a few optimization
Skip adding obvious equalities or disequality
* removed some optimisations
* better handling of backtracking
* stupid segfault
Add m_subterm to the trail
* Update src/smt/theory_datatype.h

* Initial plan
* Convert plain enums to enum class in EUF module
- Convert eq_status in euf::ac_plugin to enum class
- Convert undo_kind in euf::ac_plugin to enum class
- Convert undo_t in euf::arith_plugin to enum class
- Convert to_merge_t in euf::egraph to enum class
- Update all usage sites to use scoped enum syntax

* Convert more plain enums to enum class
- Convert state enum in substitution class
- Convert instruction enum in generic_model_converter class
- Convert eq_type enum in bit2int class
- Update all usage sites to use scoped enum syntax

default behavior is conservative: if the body of a recursive function contains uninterpreted variables they are not rewritten.
Model evaluation will bind values to uninterpreted variables so the filter should not apply here.
add simplification rule for at(x, offset) = ""
Introducing j just postpones some rewrites that prevent useful simplifications. Z3 already uses common sub-expressions.
The example highlights some opportunities for simplification, noteworthy at(..) = "".
The example is solved in both versions after adding this simplification.
* 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).
