[llama.cpp convert_hf_to_gguf.py] "Missing or incomplete model files" / "Mismatch between weight map and model parts" - partial safetensors download

Cause (Documented platform behavior): Converter compares tensor names in index weight_map vs tensors found in parts. Fix status: documented_behavior Other error fragments: - Mismatch between weight map and model parts for tensor names: Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/ggml-org/llama.cpp/a97cce86a8addeb9f40cba7a261c94b1f0c576cb/conversion/base.py (official_docs, unknown, documented_behavior): Raises "Missing or incomplete model files" when index tensors are absent from parts; otherwise mismatch error with Missing/Extra lists.
