Cut 1.2.3 with a shutter that never waits on GPS

Bound the geotag fix with a 2 s deadline and prewarm it at launch, queue a
shot pressed before the camera session binds and replay it, pass the options
argument capturePhotoToFile requires, save through the native path so the
media permission is not needed, and release the Skia surface and bitmap after
every export. Store the JS bundle uncompressed and load the export pipeline on
demand. Note in RELEASE_NOTES.md that none of this moved the tap threshold.
