PR Summary

Low Risk
Low risk: changes are primarily new tests plus a small, well-covered tweak to JSON single-quote repair logic that could slightly alter parsing of malformed LLM responses.

Overview
Bumps crate version to 0.5.27 and extends test coverage across config, triage, and prompt-guidance generation to lock in expected defaults/edge cases.

Improves convert_single_quoted_json_to_double to correctly handle escaped apostrophes inside single-quoted JSON-like strings (e.g. don\'t), and adds parsing tests for single-quoted findings wrappers and apostrophe handling.
