A reliability and polish release focused on protecting your data, finishing two long-promised keyboard features, and fixing the Window Switcher (Opt+Tab) rough edges.

🐛 Fixed

• Pinned items no longer disappear on their own. The old per-type
  history limit ran on every save and silently deleted pinned items
  once the text cap was hit — it only checked isFavorite, not
  isPinned. That's the source of the "my pin went away" reports.
  All protected categories (pinned, starred, snippet, encrypted) are
  now excluded from pruning by predicate.
• Window Switcher (Opt+Tab) no longer gets stuck open. Releasing
  Option now reliably dismisses the panel — and commits your
  selection by raising the chosen window, the way Cmd+Tab does on
  stock macOS. (Triple-layer detection: global monitor + local
  monitor + 150ms safety poll, so the option-release event can't be
  missed.)
• Simulator / portrait windows no longer break the Switcher layout.
  Cards now use a uniform 16:10 frame regardless of the source
  window's aspect ratio. Portrait windows letterbox inside their card
  instead of stretching the whole row.
• Switcher second row is now visible. Pressing Tab to cycle past
  the first row auto-scrolls the grid so the highlighted card stays
  on screen.
• Quick Preview arrow keys actually work now (closes #6). The
  footer advertised "↑↓ navigate" but the controller only handled
  ESC and 1–9. Added: ↑↓ navigation with wrap-around, ⏎/numpad Enter
  to paste the highlighted item, hover/keyboard selection stay in
  sync.
• Single-window Dock Preview no longer leaves empty space on
  the right in small preview mode.
• Search field stays focused when filtering returns no results.

✨ New

• Storage auto-prune (Settings → General → Storage). Two
  independent caps for text and image history, with hard-delete +
  on-disk image file cleanup. Default 100 text / 20 image. Pinned,
  starred, snippets and encrypted items are never pruned.
• "Clean now" button + live usage summary ("19 history · 19 total
  · 799 KB images") for one-click manual cleanup.
• Window Switcher full keyboard navigation: Tab / Shift+Tab to
  cycle, ←↑ previous / →↓ next, Enter to confirm, Escape to cancel.
• Quick Preview is now enabled by default for new installs —
  one of Clippy's most-loved features was hidden behind a toggle
  most users never found. Existing users keep their chosen value.

🔧 Improved

• Storage uses a background context and batches every 25 inserts,
  so cleanup never blocks the hot path of capturing a copy.
• One-shot prune on app launch clears any overgrowth from older
  versions that didn't have auto-pruning.
• Settings migration: the old per-type historyLimit and
  imagesLimit values are carried over to the new
  historyTextLimit / historyImageLimit settings, so upgrading
  users keep their chosen values instead of getting reset to
  defaults.
