expected< std::vector< uint8_t > >	signet::forge::compress (Compression codec, const uint8_t *data, size_t size)
	Compress data using the specified codec via the global CodecRegistry.
expected< std::vector< uint8_t > >	signet::forge::decompress (Compression codec, const uint8_t *data, size_t size, size_t uncompressed_size)
	Decompress data using the specified codec via the global CodecRegistry.
Compression	signet::forge::auto_select_compression (const uint8_t *sample_data, size_t sample_size)
	Automatically select the best available compression codec.

Detailed Description

Compression codec interface and registry for Signet Forge.

Provides:

• CompressionCodec: Abstract base class for all compression codecs
• CodecRegistry: Thread-safe singleton registry of codec implementations
• compress() / decompress(): Convenience functions using the registry
• auto_select_compression(): Heuristic codec selection based on availability

Concrete codec implementations (Snappy, ZSTD, LZ4, GZIP) register themselves via CodecRegistry::instance().register_codec() at startup. UNCOMPRESSED is handled inline without a registered codec.
