Move reset, parameter copy, and default policy resolution from
ZSTD_makeCCtxParamsFromCParams into Rust through a pointer-based ABI function.
Keep the private LDM adjustment and its invariants in C while Rust owns the
stable parameter-object policy and focused reset/resolution coverage.
Test Plan:
- worker git diff and capped format checks
- parent capped root clippy and native build
- parent capped upstream make -j1 -C tests test
- parent capped CLI clippy and tests
All parent verification is serial under a 40 GiB virtual-memory cap. Standalone
root Rust unit linking remains unavailable because the crate imports C-owned
bridge symbols.
