/**
 * Browser compression utilities
 *
 * Supports multiple formats:
 * - deflate-raw: Raw DEFLATE (for ZIP files)
 * - gzip: GZIP format (for tar.gz, HTTP compression)

 * Primary: CompressionStream API (Chrome 103+, Firefox 113+, Safari 16.4+)
 * Fallback: Pure JS DEFLATE implementation for older browsers
 *
 * Worker Pool: Optional off-main-thread compression/decompression
 * to prevent UI blocking for large files.
