Module compression 

Vector compression — thin facade module.

The implementation lives in sibling modules:

• crate::compression_types: codec/config enums, traits, metrics, analysis.
• crate::compression_codecs: concrete codec implementations.
• crate::compression_io: factory, method equivalence, adaptive compressor.
