Ben-reported: picker opened on every activation. AppModel.init set region = nil and never
read UserDefaults back; saving worked, every launch forgot it. init now loads via
loadPersistedRegion() (decode + isStillValid). Selftest phase 2 writes a known region,
reloads through the same path, asserts the rect, restores the user's stored value.
Coordinator ran it: PICKER-SELFTEST PASS + REGION-PERSIST PASS, 90/90 tests green.

Root cause: RegionPickerView lacked acceptsFirstMouse — as an LSUIElement accessory app
Shotdeck is never active when the hotkey fires, so the user's first click on the overlay
was refused and the drag never started. Also plumbs the monitored event's location through
the controller (hardware-cursor reads made the chain untestable). Adds PickerSelfTest
(SHOTDECK_PICKER_SELFTEST): posts synthetic mouse events through the app's own queue,
asserts the exact CaptureRegion, saves a mid-drag overlay bitmap. Coordinator ran it:
PICKER-SELFTEST PASS rect=(200.0, 729.0, 400.0, 300.0); overlay bitmap shows dim+punch+chip.
