[Bug] Model download progress halts at a fraction of 100% due to full-repo sizing

[akramcodez]

Description

The Python script gets total repo size using total_size = sum(s.size for s in siblings). This calculates the size of all files on HuggingFace, including multiple quantizations. As MLX downloads only a subset, the progress percent stops early (e.g., at 20%) and jumps abruptly to "done".

Environment

• macOS version: macOS 14.0
• Apple Silicon: M2
• Node version: v22.0.0
• Python version: 3.12
• Nanotune version: 1.7.0

Steps to Reproduce

1. Download a large HuggingFace repository containing both .bin and .safetensors files using nanotune.
2. Observe the download progress bar.

Expected Behavior

The progress bar goes smoothly from 0 to 100%.

Actual Behavior

The progress bar stops at ~50% and abruptly finishes.
