feat: add value decompression, command autocomplete meta, and TTL in key list}
- Add automatic decompression for compressed Redis values (gzip, zlib, zstd, lz4, snappy, brotli, zip) with compression metadata reporting (algorithm, original/decompressed size, ratio) across all key types - Add redis-command-hints.mjs with static syntax hints for 200+ Redis commands including modules (JSON, Search, TimeSeries) - Add redis-command-meta.mjs to build categorized command metadata from redis.command() output for autocomplete support - Send commandsMeta in connection info response for client-side use - Fetch TTL alongside type in key listing pipeline and include keysInfoFetchedAt timestamp in response - Switch pub/sub from pmessage to pmessageBuffer to preserve raw binary data (e.g. msgpack from socket.io-adapter) - Add dependencies: @msgpack/msgpack, fzstd, lz4js, snappyjs - Bump version to 2026.4.312
