ZDDC c22bb19dab perf(server): gzip compression middleware on the entire mux ... Add github.com/klauspost/compress/gzhttp wrapper around the request handler. With MinSize(1024), responses ≥ 1 KB get gzip-encoded when the client advertises Accept-Encoding: gzip; smaller bodies + 304 Not Modified pass through unchanged. The wrapper auto-appends Vary: Accept-Encoding (compatible with the existing Vary: Accept on directory.go's content-negotiated path). Live-tested against zddc-server -root /tmp/empty: GET / w/ Accept-Encoding: gzip → 20.9 KB compressed (was 80.9 KB uncompressed). 74% reduction. Decompresses cleanly back to the original bytes. Helps every code path that bypasses Caddy: devshell pods, local dev binaries, tests, anywhere zddc-server is hit directly. Production behind Caddy already had compression at the proxy layer; this just makes the Go server self-sufficient. Tests in cmd/zddc-server/main_test.go cover: - large body + Accept-Encoding → compressed + Vary header - small body → not compressed (under MinSize) - no Accept-Encoding header → plain bytes		2026-05-03 23:31:18 -05:00
