ddidderr bd9ca5115d feat(decompress): move DCtx prefix copy into Rust ...

Move the `ZSTD_copyDCtx` prefix-copy leaf into the Rust decompression module.
Rust uses the C-projected address of `inBuff` to preserve the exact private
context cutoff, while C retains the configuration-dependent context layout
and shallow-pointer ownership semantics. Add a focused boundary test and
remove the now-unused C copy helper.

Test Plan:
- ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo fmt --manifest-path rust/Cargo.toml -- --check
- ulimit -v 41943040; CARGO_BUILD_JOBS=1 cargo test --manifest-path rust/Cargo.toml copy_prefix -- --nocapture
- 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
