MacStorageAtlas 0.0.2 — Real on-disk size

What's new

Real on-disk size measurement 🧮

MacStorageAtlas now measures how much space files actually occupy on disk
instead of their logical length. Undownloaded cloud placeholders — iCloud Drive,
OneDrive, kDrive and similar "dataless" files — now count as roughly zero,
so totals match what Finder and du report.

• New scan option "Measure space actually used on disk" — on by default.
  Turn it off to fall back to the full logical file size.
• On macOS the on-disk footprint is read via stat (st_blocks × 512).
• No accidental downloads: scanning only reads file metadata and never
  materializes dataless cloud files.
