Pull request overview

Updates LLamaSharp’s native interop layer to match llama.cpp commit c0c7e147e7efa6c5858754b47259ba4880f8a906, including new context parameters and updated MTMD interop signatures.

Changes:

• Added support for new llama_context_params fields (n_rs_seq rollback snapshots and context_type / MTP support) and surfaced them through IContextParams and conversions.
• Updated MTMD decoder position ABI (adds z component and introduces pos_0 argument in relevant P/Invokes).
• Removed the llama_params_fit P/Invoke (and its status enum) and updated binary release ID to the new upstream snapshot.
