ddidderr d316a14ec3 feat(rust): export public sequence helpers
Move the context-free ZSTD_sequenceBound and ZSTD_mergeBlockDelimiters APIs
into the Rust compression helper module. Preserve the public sequence ABI,
block-delimiter semantics, and unsigned literal-length wrapping behavior while
leaving context-driven sequence generation in C.

Test Plan:
- cargo clippy
- cargo clippy --benches
- cargo clippy --tests
- cargo +nightly fmt
- cargo test zstd_compress_api::tests -- --nocapture
- cargo test --target i686-unknown-linux-gnu zstd_compress_api::tests

ddidderr 3e2635f45d feat(rust): export compression bound from Rust
Move the context-free public ZSTD_compressBound ABI into Rust while leaving
the stateful compressor context in C. The Rust implementation preserves the
size-width-specific input limit, macro arithmetic, and srcSize_wrong error
contract used by C callers.

Test Plan:
- cargo clippy
- cargo clippy --benches
- cargo clippy --tests
- cargo +nightly fmt
- cargo test zstd_compress_api::tests -- --nocapture
- cargo test --target i686-unknown-linux-gnu zstd_compress_api::tests
- make -B -C lib -j2 libzstd.a
- fuzzer -s5346 -i1 --no-big-tests
