ddidderr 66e7799f04 refactor(compress): move sequence generation policy to Rust ...

ZSTD_generateSequences() previously mixed public parameter validation,
temporary-output allocation, sequence-collector setup, compression, and cleanup
inside the C translation unit. Move that ordering into Rust behind callbacks so
private ZSTD_CCtx and SeqCollector layouts remain C-owned. The adapter retains
C allocation, context access, and the existing ZSTD_compress2 operation, while
Rust guarantees temporary-output cleanup after collector setup failures and
compression errors and preserves the original target-block-size and worker
parameter checks.

Focused callback tests cover validation-before-allocation, cleanup on setup
failure, and successful callback ordering/count publication.

Test Plan:
- `cargo fmt --manifest-path rust/Cargo.toml --all -- --check` -- passed
- `ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/Cargo.toml generate_sequences --lib` -- passed (3 tests)
- `ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/Cargo.toml --all-targets` -- passed (762 tests)
- `ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings` -- passed
- `ulimit -v 41943040; make -j1` -- passed
