Route ordinary complete-input ZSTD_compressStream2 calls through the Rust frame compressor while retaining the C state machine for partial, advanced, and dictionary-backed streams. Track explicit maxBlockSize requests so the migrated path preserves the original byte-identical default behavior, and extend the C archive smoke test across context reuse and fallback cases.
Test Plan:
- cargo clippy --manifest-path rust/Cargo.toml
- cargo clippy --manifest-path rust/Cargo.toml --benches
- cargo clippy --manifest-path rust/Cargo.toml --tests
- cargo test --manifest-path rust/Cargo.toml --no-default-features --features compression (133 passed)
- make -B -C tests -j2 test-rust-lib-smoke and ./tests/rustLibSmoke
- make -B -C tests -j2 test-zstream (passed, including both APIs and maxBlockSize case 78)
