perf(compression): reuse zlib writers across DeflateData calls

DeflateData built a new zlib writer for every outbound message and
discarded it, allocating about 800 KB per call. Keep writers in a
sync.Pool and Reset them onto each call's buffer instead.

Output is byte-identical (golden tests unchanged). Locally, a ~90 byte
payload went from ~19 µs and 814 KB/op to ~11.6 µs and ~250 B/op.
