0.1.1

Compliance and hardening pass ahead of community-directory submission.

• Data-folder hiding now uses Obsidian's Excluded Files. The folder is kept out
  of search, graph, and the quick switcher and dimmed in the file explorer, instead
  of being removed via injected CSS. Files are untouched on disk.
• Removed the default Quick Add hotkey. The Quick Add Task command is still
  available — assign your own shortcut under Settings → Hotkeys if you want one.
• Resolve theme colors and hide the data folder through the active window/document,
  for correct behavior in pop-out windows.
• Use Obsidian's styling APIs instead of direct style assignment, and drop unneeded
  !important and CSS the linter flags on older Obsidian versions.
• Release assets now ship with build-provenance attestations.
