support --hf-repo like llama-server

[khimaros]

this would be a really great convenience flag!

[CrispStrobe]

This is already supported! Two equivalent syntaxes:

# Shorthand — repo:file in one flag
crispasr --hf-repo cstr/parakeet-tdt-0.6b-v3-GGUF:parakeet-tdt-0.6b-v3-q4_k.gguf -f audio.wav

# Two-flag — same as llama-server
crispasr --hf-repo cstr/parakeet-tdt-0.6b-v3-GGUF --hf-file parakeet-tdt-0.6b-v3-q4_k.gguf -f audio.wav

# Or with -m for the filename (also works)
crispasr --hf-repo cstr/parakeet-tdt-0.6b-v3-GGUF -m parakeet-tdt-0.6b-v3-q4_k.gguf -f audio.wav

Short aliases: -hfr for --hf-repo, -hff for --hf-file. Implies --auto-download. Downloads are cached in --cache-dir (default ~/.cache/crispasr/).

crispasr --help shows the flags under the download section.

Implemented in b77a74e — --hf-repo flag added. Use crispasr --hf-repo org/repo-name model.gguf to download models directly from any HuggingFace repo.
