v1.4.1

Added

• Add a composable Prompt Builder with independent redesign scope, structure, and visual-system
  options. Users can create, edit, and reuse their own options; combinations compile into one
  prompt and bookmarks retain stable snapshots of every selected custom instruction.
• Add hover deletion and keyboard-accessible multi-select deletion to the Viewer run gallery,
  including confirmation, active-run protection, and partial-failure recovery.

Changed

• Ship the Windows app as an icon-bearing, single-file GUI executable with no console window.
  GitHub releases also retain a compact ZIP for the automatic updater, with no loose web or
  node_modules directories.
• Upgrade Connections settings sync to the multi-device-safe 1.2 engine. Empty accounts seed in
  one operation, nested concurrent edits no longer overwrite unrelated preferences, and shutdown
  gets five seconds to flush before a stuck token or network request is cancelled.
