ddidderr f882006e7a feat(compress): move CCtx workspace policy into Rust ...

Move the CCtx reset workspace resize decision, index-reset mutation,
reservation order, private-pointer publication order, and clear boundary into
Rust. Keep the workspace allocator and private ZSTD_CCtx layout operations in
C behind callbacks, with matching C/Rust layout assertions.

Add focused tests for the no-resize, resize, and static-resize error paths so
the callback order and mutation boundaries remain explicit.

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 -j1`
- `ulimit -v 41943040 && make -j1 -C tests test-zstream ZSTREAM_TESTTIME=-T2s`
- `ulimit -v 41943040 && make -j1 -C tests test-fuzzer FUZZERTEST=-T3s FUZZER_FLAGS=--no-big-tests`
- `ulimit -v 41943040 && cargo fmt --manifest-path rust/Cargo.toml -- --check`
- `git diff --check`
