Zstd compress

POST /api/zstd-compress

Compress arbitrary bytes with Zstandard. Standard .zst frame any tool can decompress (`zstd -d`, libraries, etc.). Configurable level 1–22.

Takes any bytes and returns a Zstandard (.zst) compressed frame — a modern alternative to gzip that typically produces 30–50% smaller output at similar (or better) speeds. Decompresses cleanly with `zstd -d` or any zstd-compatible library. Compression level ranges 1–22. `3` is the upstream default; `19+` is "long mode" with substantially higher CPU cost — useful for archival workloads where decompression speed is what matters.
