#7791 reports on using model values during lex optimization that break soft constraints.
This is an artifact of using optimization where optimal values can be arbitrarily close to a rational.
In a way it is by design, but we give the user now an option to control the starting point for epsilon when converting infinitesimals into rationals.

* chipping away at the new code structure
* comments
* debug infinite recursion and split cubes on existing split atoms that aren't in the cube
* share lemmas, learn from unsat core, try to debug a couple of things, there was a subtle bug that i have a hard time repro'ing
* merge
* fix#7603: race condition in Ctrl-C handling (#7755)
* fix#7603: race condition in Ctrl-C handling
* fix race in cancel_eh
* fix build
* add arithemtic saturation
* add an option to register callback on quantifier instantiation
Suppose a user propagator encodes axioms using quantifiers and uses E-matching for instantiation. If it wants to implement a custom priority scheme or drop some instances based on internal checks it can register a callback with quantifier instantiation
* missing new closure

* resolve bad bug about l2g and g2l translators using wrong global context. add some debug prints
* initial attempt at dynamically switching from greedy to frugal splitting strategy in return_cubes. need to test. also there is some bug where the threads take forever to cancel?
* Update RELEASE_NOTES.md
* resolve bug about not translating managers correctly for the second phase of the greedy cubing, and the frugal fallback
* remove unused square-free check
Signed-off-by: Lev Nachmanson <levnach@hotmail.com>
* add some debug prints and impelement internal polynomial fix
* add some comments and debug m_assumptions_used
* redo greedy->frugal strategy so we don't split on existing cubes in frugal at all (eliminate the incorrect/wasteful step by processing current batch first)
* set up initial scaffolding for sharing clauses between threads and batch manager. needs some reworking/debug still

* 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).
