ddidderr b4ad7ee796 feat(compress): move window update policy into Rust ...

Move the shared prefix and external-dictionary window transition into Rust
through a five-field projection. Preserve wrapping pointer-address arithmetic,
contiguous detection, short-dictionary clamping, and overlap clipping while C
retains the private match-state container and copies the projected fields back.

Test Plan:
- ulimit -v 41943040; CARGO_BUILD_JOBS=1; cargo test --manifest-path rust/Cargo.toml
- ulimit -v 41943040; CARGO_BUILD_JOBS=1; cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
- ulimit -v 41943040; make -B -C programs -j1 zstd
- ulimit -v 41943040; make -C tests -j1 test-zstream ZSTREAM_TESTTIME=-T1s
