* Add comprehensive API special relations tests
- Implement tests for all 5 special relations API functions:
* Z3_mk_linear_order - Linear order relation
* Z3_mk_partial_order - Partial order relation
* Z3_mk_piecewise_linear_order - Piecewise linear order relation
* Z3_mk_tree_order - Tree order relation
* Z3_mk_transitive_closure - Transitive closure of a relation
- Test coverage achieved: 100% (5/5 lines) in src/api/api_special_relations.cpp
- Added comprehensive test cases covering:
* Basic functionality with different sorts
* Different index parameters
* Expression creation and integration
* Edge cases and variations

Added comprehensive test coverage for Z3's pseudo-boolean constraint API functions, improving coverage from 0% to 100% for src/api/api_pb.cpp.
- Created comprehensive test suite in src/test/api_pb.cpp
- Added test registration in src/test/main.cpp and src/test/CMakeLists.txt
- Implemented tests for all 5 API functions:
* Z3_mk_atmost: at most k variables can be true
* Z3_mk_atleast: at least k variables can be true
* Z3_mk_pble: weighted pseudo-boolean less-than-or-equal constraint
* Z3_mk_pbge: weighted pseudo-boolean greater-than-or-equal constraint
* Z3_mk_pbeq: weighted pseudo-boolean equality constraint
- Comprehensive test cases covering edge cases, negative coefficients, zero thresholds, empty arrays, and complex scenarios
- All tests pass successfully with 100% coverage achieved
Coverage improvement: api_pb.cpp went from 0% (0/64 lines) to 100% (64/64 lines)

* Daily Test Coverage Improver: Add comprehensive API Datalog tests
This commit adds comprehensive test coverage for Z3's Datalog/fixedpoint API functions, improving coverage from 0% to 17% (84/486 lines) in src/api/api_datalog.cpp.
Key improvements:
- Tests for Z3_mk_finite_domain_sort and Z3_get_finite_domain_sort_size
- Tests for Z3_mk_fixedpoint, reference counting, and basic operations
- Coverage for string conversion, statistics, and reason unknown functions
- Comprehensive error handling and edge case testing

* Initial plan
* Add comprehensive test coverage for math/lp and math/polynomial modules
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Finalize test coverage improvements with corrected implementations
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Fix compilation errors in test files
- Fix algebraic_numbers.cpp: Simplified tests to use basic algebraic operations without polynomial manager dependencies
- Fix polynomial_factorization.cpp: Corrected upolynomial::factors usage and API calls
- Fix nla_intervals.cpp: Changed 'solver' to 'nla::core' and fixed lar_solver constructor
- Fix monomial_bounds.cpp: Updated class names and method calls to match current NLA API
These changes address the scoped_numeral compilation errors and other API mismatches identified in the build.

plugin setting allows adding equality saturation within the E-graph propagation without involving externalizing theory solver dispatch. It makes equality saturation independent of SAT integration.
Add a special relation operator to support ad-hoc AC symbols.
This fixes encode roundtripping for all printable ASCII characters.
In particular, this now leaves a plain '\' untouched by the
encoding logic, instead of converting it to escaped hex-digits.
It also adds unit testing covering this specific zstring encoding
property, in order to avoid future regressions.
