* Initial plan
* Update z3 codebase to use std::string_view (except z3++.h)
- Updated params.cpp/h to use string_view internally for parameter descriptions
- Updated trace.h/cpp to accept string_view for trace tag functions
- Updated hash.h/cpp to use string_view for string_hash function
- Updated all callers of string_hash to use string_view
- Properly handled nullptr to empty string_view conversions
- All tests passing

* Add missing string_view includes to headers

* restore more aggressive pruning in search tree
* restore where we close children to be correct
* add core strengthening check
* fix recursion bug
* less strict core propagation
* old search tree version
* restore search tree patch
* remove flag
* debugging inconsistent end state with search, some changes need to be made in search tree, only backtrack should be closing nodes, I think the bug is when we do find_highest_attach for nonchronological backjumping, you might get to a point where the sibling is closed, so then we need to resolve further up the tree
* clean up code, fix deadlock
* delete test files
* clean up

* Initial plan
* Add [[nodiscard]] to AST factory functions and modernize iterator loops
- Added [[nodiscard]] attribute to key factory functions in ast.h:
- All mk_app() variants for creating application nodes
- All mk_func_decl() variants for creating function declarations
- All mk_const() variants for creating constants
- All mk_sort() variants for creating sorts
- mk_var() for creating variables
- mk_quantifier(), mk_forall(), mk_exists(), mk_lambda() for quantifiers
- mk_label(), mk_pattern() and related functions
- Converted iterator loops to range-based for loops in:
- src/util/region.cpp: pop_scope()
- src/util/dec_ref_util.h: dec_ref_key_values(), dec_ref_keys(), dec_ref_values()
- src/util/mpf.h: dispose()
- src/util/numeral_buffer.h: reset()

* Modernize additional iterator loops to range-based for loops
- Converted iterator loops to range-based for loops in:
- src/api/api_ast_map.cpp: Z3_ast_map_keys() and Z3_ast_map_to_string()
- src/api/c++/z3++.h: optimize copy constructor and add() method
- src/opt/wmax.cpp: mk_assumptions()
Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Revert changes to z3++.h for C++ version compatibility
Revert the range-based for loop changes in src/api/c++/z3++.h to maintain
compatibility with older C++ versions that users may rely on. The C++ API
wrapper must support down-level C++ standards for backward compatibility.

* Initial plan
* Fix DEL character encoding in string literals
Change condition from `ch >= 128` to `ch >= 127` to include the DEL
character (U+007F, 127) in escaped output. This ensures that the
non-printable DEL control character is properly escaped as \u{7f}
instead of being printed directly.
Also add test cases for DEL and other control characters.

* Add cube tree optimization about resolving cores recursively up the path, to prune. Also integrate asms into the tree so they're not tracked separately (#7960)
* draft attempt at optimizing cube tree with resolvents. have not tested/ran yet
* adding comments
* fix bug about needing to bubble resolvent upwards to highest ancestor
* fix bug where we need to cover the whole resolvent in the path when bubbling up
* clean up comments
* close entire tree when sibling resolvent is empty
* integrate asms directly into cube tree, remove separate tracking
* try to fix bug about redundant resolutions, merging close and try_resolve_upwards into once function
* separate the logic again to avoid mutual recursion
* Refactor search tree closure and resolution logic
Refactor close_with_core to simplify logic and remove unnecessary parameters. Update sibling resolvent computation and try_resolve_upwards for clarity.
* apply formatting
