 ### Added
 
 - **get_full_metadata raw_metadata returns all tags**: `raw_metadata` now consistently includes every tag present in the file per format. RIFF INFO extractor and \_RiffManager no longer filter by `RiffTagKey`—every INFO chunk FourCC (known or custom) is returned in `raw_metadata["riff"]["parsed_fields"]`, with a parsing guard that only accepts valid 4-byte printable-ASCII FourCCs. Integration coverage for custom ID3v2 TXXX, custom Vorbis comments, ID3v1 parsed fields, custom RIFF FourCCs, and BWF bext; test helpers for custom TXXX and custom RIFF INFO fields. Documentation updated for raw-metadata guarantees.
