chore(release): v0.11.5

One fix since v0.11.4: a video in a picture-in-picture window no longer drops
to audio-only partway through, replaying from wherever the picture had been
when the window opened.

Two independent faults had to line up for it. The player's position variable is
written only by a requestAnimationFrame loop while playing, and RAF stops for a
document that is not being rendered -- which an Android activity behind a PiP
window is not; the `timeupdate` handler that would have covered the gap had
gated itself on `!isPlaying` since the first commit. And PiP and the
background-audio handoff, nominally alternatives, could both be armed at once,
with a single `isInPictureInPictureMode` sample taken inside onStop() standing
between them.

The frozen position was not confined to the handoff: the seek bar, resume
points and the progress reported to Jellyfin all read the same variable, so all
three stood still for as long as a PiP window was open.

Version stamped with scripts/set-version.sh. defect-windows.md records DR-265
under the present-since/reachable-since gap: defective since v0.0.1, but only
hittable once PiP started working on the HTML5 path in v0.5.3.
