feat(core): Improve type inference and BPM detection
This commit addresses a high number of files being incorrectly classified as "unknown" and fixes bugs where numbers in machine names were misidentified as BPM values. The changes significantly improve accuracy, especially for collections like "Samples from Mars". The primary issues were an incomplete machine token list and overly simplistic type inference logic. These have been corrected by expanding the configuration and making the extraction algorithms more robust. Key improvements: config.py: - Expanded `MACHINE_TOKENS` with over 20 new synthesizer and drum machine names (e.g., `DX100`, `SH5`, `SYS100M`, `MS10`, `SK1`). This prevents numbers in their names from being parsed as BPMs. - Added more pack-specific rules to `PACK_DEFAULT_TYPE` to provide better fallbacks for vendors like `DX100`, `Soviet`, etc. - Added several specific keywords to `TYPE_MAP` (e.g., `syntom`, `pipeorgan`) for more direct type matching. extractors.py: - Enhanced `infer_type_from_path()` to tokenize directory names. It can now correctly identify the type from folders with prefixes, such as "08. Kicks" or "8. Tambourine". - Updated `infer_type_from_tokens()` to select the *last* matching type keyword in a filename, assuming it is the most specific. For example, "Synth Tom" is now correctly identified as `tom`, not `instrument_synth`. - Refined `extract_bpm()` to ensure that once a numeric token is identified as a BPM, it is consumed and not passed along as a descriptor.
