splash: cut the post-settle hold to 0.3s

[m4ttheweric]

The splash could not fade for 2.0s: 1.0s of estimated drop-in animation plus
1.0s of holding the settled mark. The second second read as a stall rather
than as a beat, so it drops to 0.3s and the floor becomes 1.3s.

Dismissal is unchanged otherwise: still the later of this floor and the
active app's first navigation finishing, still capped at 8s.

One constant and a comment. Skipping the CodeRabbit wait with Matt's
agreement, since there is nothing here for it to read.
