ddidderr fec11ae7d0 feat(compress): move sequence-store branch policy into Rust ...

Move buildSeqStore's preloaded external-sequence, LDM, external-producer,
fallback, and ordinary matchfinder branch ordering into Rust. Keep the
private CCtx, matchfinder, LDM, and producer operations behind narrow C
callbacks, add ABI layout assertions, update the Rust boundary documentation,
and cover each policy branch with focused tests.

Test Plan:
- cargo fmt --manifest-path rust/Cargo.toml -- --check
- ulimit -v 41943040 && CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/Cargo.toml --lib (690 passed)
- ulimit -v 41943040 && CARGO_BUILD_JOBS=1 cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
- ulimit -v 41943040 && MAKEFLAGS=-j1 make -B -C programs -j1 zstd
- ulimit -v 41943040 && MAKEFLAGS=-j1 make -C tests -j1 test-zstream ZSTREAM_TESTTIME=-T1s (84 tests and both short fuzz rounds passed)
