Address review feedback: fix tiebreaker map, error handling, regex patterns

- Add BlueskyItem/TruthSocialItem to _ITEM_SOURCE_MAP (wrong tiebreaker)
- Add bluesky/truthsocial to _DEFAULT_TIEBREAKER
- Log HTTPError in select_openai_model instead of silent fallback
- Remove overly broad 'or.*for' from comparison regex (false positives)
- Remove bare 'will' from prediction regex (misclassifies feature queries)
- Narrow brave_search except clauses to ValueError/TypeError
- Fix stale comments: pricing table, docstrings, penalty descriptions
