Subject: [PATCH] feat: cpm download-weights command with HF Hub provider (#44)

Adds:
- cpm download-weights --provider hf --kind <raw|wide> --type <gguf|safetensors> <name>
- weights.Provider interface for future providers (models.dev)
- HF Hub search via public API (library=gguf, sorted by downloads)
- Large-file streaming download with SHA-256 verification
- Decoupled progress reporting (TextProgress/NoopProgress callbacks)
- Auto-download when cpm install encounters manifest brain.*.weights.remote
- cpm init --template gguf-model for model publishers
- Raw model skip-if-exists; wide model always overwrites
