- Recognized preformatted chat context in message-preproc and bypassed paired-tag stripping that consumed the entire envelope.
- Integrated scaffolding-tag removal in low-signal title prefilter.
- Added corresponding tests for formatTitleUserMessage and isLowSignalTitleInput.
- Centralized message preprocessing for tiny models to handle noise removal, code block stripping, and context formatting.
- Updated title generation logic to support self-closing tags and improved robustness against partial markers.
- Added structured guidance and system prompts for small models to prioritize output consistency.
- Implemented a title-generation benchmark harness and expanded test coverage for message preprocessing.
