v0.2.2

Added

• Status now reports only exceptional runtime-cache state, distinguishes
  identified interrupted staging from untracked data, and prints exact resume
  and cleanup commands.
• Download staging now records its repository and resolved commit so crash
  residue can be diagnosed without recursively scanning large archives.
• Verification failures now show categorized file-level causes and actionable
  next commands.
• Snapshot, download, checksum, repair, and publication paths now share
  canonical-path, duplicate-path, regular-file, and symlink safety checks.

Fixed

• Verification no longer imposes format-specific file or layout requirements;
  model payload formats are treated as opaque bytes.
• Forced cache cleanup now refuses to run while repository or runtime-cache
  locks show active work.
