Rebuild held input after lifecycle resets

A focus flip, visibility flip, joystick add/remove, or resume reset all
held input, and a still-held direction never re-fires keypressed, so any
spurious reset (macOS Bluetooth re-enumeration fires joystickadded with
no hotplug) parked the player until every direction was re-pressed.
Reconcile from device ground truth after each reset; only what is
physically down comes back, so swallowed releases still clear.
