…d ensure version bump only on actual changes; apply consistent changed = changed or (previous != info) logic for table and module_operators and removals

Summary: The PR adds parsed module caching to improve performance by avoiding redundant parsing of unchanged Prolog files. The implementation is well-designed with proper cache invalidation based on file modification time, operator table version, character conversions, and conditional compilation state. Tests verify cache reuse and invalidation behavior. No security issues, bugs, or style violations found.

Code Review
This pull request introduces a parsed module caching mechanism to the Prolog interpreter, aiming to improve performance by avoiding redundant parsing. Key changes include adding a ParsedModuleCacheEntry TypedDict and associated caching logic within vibeprolog/interpreter.py, which now checks for cached parsed items based on file modification time, operator table version, character conversions, and conditional compilation state. The consult method was updated to leverage this cache, and new tests were added in tests/test_module_parsing_cache.py to verify cache reuse and invalidation on file changes. Additionally, the OperatorTable in vibeprolog/operators.py now tracks a version number that increments upon operator definition changes, ensuring cache consistency. Documentation was updated in docs/FEATURES.md, docs/LIBRARY_STATUS.md, and docs/SYNTAX_NOTES.md to reflect the new caching feature and updated library loading statistics, including library/xpath.pl now loading successfully, and changes in error messages for library/numerics/special_functions.pl, library/numerics/testutils.pl, library/ordsets.pl, and library/ugraphs.pl. Review comments suggest removing an unused all_items variable in _process_parsed_items for clarity and simplifying a conditional logic for the changed flag in _define_single within the operator table.

The variable all_items is initialized and extended within the _process_parsed_items function, but it is never used. It appears to be a remnant from a previous implementation and can be safely removed to improve code clarity and maintainability.
def _process_parsed_items(
parsed_items: list[Clause | Directive],
last_pred: tuple[str, str, int] | None,
) -> tuple[str, str, int] | None:
for item in parsed_items:
expanded_item = self._apply_term_expansion(item)
if hasattr(expanded_item, "elements") and isinstance(expanded_item.elements, list):
items_to_process = list(expanded_item.elements)
else:
items_to_process = [expanded_item]
last_pred = self._process_items(
items_to_process,
source_name,
closed_predicates,
last_pred,
)
return last_predReferences
- Code should be easy to understand for all team members. Removing unused code improves readability and maintainability. (link)

all_items in _consult_code
Remove the unused all_items = [] variable and related code, as items are now processed immediately instead of collected.
- all_items = []
+
changed flag logic in _define_single
The changed flag can be simplified by directly setting it to True when changes occur, rather than using or operations.
- changed = changed or (previous != info)
+ changed = True
And similar for other places.

Summary: The PR implements parsed module caching to improve performance by avoiding redundant parsing of unchanged Prolog files. The implementation includes proper cache invalidation based on file modification time, operator table version, character conversions, and conditional compilation state. Tests verify cache reuse and invalidation behavior. Two minor code quality issues found: an unused variable and redundant flag logic.
