- New format.ts: decodeValue + detectFormat using Node.js zlib - IPC: redis:decodeValue, redis:detectFormat - StringEditor: format selector dropdown with auto-detect - Monaco editor shows decoded value, read-only for compressed formats - Auto-detect: JSON, Gzip (1f 8b), Deflate (78 xx), non-printable → Hex - i18n keys for all formats (zh-CN + en)
