[AI] Test Coverage Expansion and Refinement

[google-labs-jules]

This PR expands test coverage for eldritch-core by adding a new integration test suite for the introspection module. It specifically targets find_best_match, is_truthy, and get_type_name.

During testing, a logic gap was identified in find_best_match where an empty target string could incorrectly match against short candidates due to threshold logic. This has been fixed by adding an early return for empty targets.

Stability Report:

• tests/introspection_coverage.rs: Passed 20/20 consecutive runs locally.
