Fixes the Dock staying on the built-in display after reconnecting an external monitor even though the saved target remains selected.

- Automatically reapplies the saved target after reconnect or wake, allowing the display configuration to settle first.
- Preserves the preferred display while it is disconnected and temporarily falls back to an available display.
- Retries a limited number of times and cancels stale activation work after display changes, target changes, sleep, or quit.

Download **DockPin.zip** below, replace `/Applications/DockPin.app`, and reopen it.

Validation: 11 automated regression tests passed; macOS release build and code-signature verification passed. Physical cable reconnection still requires manual verification.
