feat(requester-node-http): add gzip compression for requests and response decompression#1603
Conversation
…onse decompression When the accept-encoding header includes gzip, request bodies are compressed with zlib.gzipSync() and a content-encoding: gzip header is added. Responses with content-encoding: gzip are decompressed via zlib.createGunzip(). Decompression errors resolve gracefully following the existing error handling pattern (never reject). Includes 8 comprehensive tests covering compression, decompression, error handling, multi-value headers, and full round-trip scenarios.

Use Buffer.byteLength() to set content-length for both compressed and uncompressed request bodies, avoiding unnecessary chunked transfer encoding overhead.
Small request bodies gain little from compression and the gzip overhead can exceed the savings. Only compress when body size >= 1024 bytes.
Release the native zlib handle promptly instead of waiting for garbage collection. Covers both the error path (decompression failure, response stream error) and the timeout path (req.abort mid-transfer).

Avoid blocking the event loop during compression. Large payloads (multiple MB) on server-side would stall all concurrent requests with the sync API. The async callback compresses on the libuv thread pool.
