## Which issue does this PR close? Part of #2411. This implements the "Support zstd metadata compression codec" tracking item without closing the broader v3 epic. ## What changes are included in this PR? - Accept `write.metadata.compression-codec=zstd` case-insensitively, using the existing default zstd level. - Generate canonical `.zstd.metadata.json` names and parse both canonical and trailing gzip/zstd suffix forms. - Detect gzip and standard zstd frames from content when reading metadata, independent of filenames. - Compress metadata with zstd when writing while preserving codec/location consistency checks. - Add an iceberg-go zstd metadata fixture and interoperability, error-path, canonicalization, transition, and round-trip coverage. No catalog-specific, dependency, lockfile, or format-version changes are included. ## Are these changes tested? Yes: - `cargo test -p iceberg --lib` — 1473 passed - `cargo fmt --all -- --check` - `cargo clippy -p iceberg --all-targets --all-features -- -D warnings` -- This is an automated message from the Apache Git Service.
