Timeouts for long requests like launch or resume timed the entire
HTTP operation. If the host was no longer reachable, we could
spend 2 minutes sitting there, even though we hadn't even made
successful contact with the host to give it our request yet.
Now we will time out a request if we can't send it in 5 seconds,
regardless of how long we want to wait for the server to respond.
Apps built with the macOS 26+ SDK default to an event loop synchronized to the display which caps input polling rates.
We have to use the plist for the opt-out, since NSApp is already set up by Qt before SDL can set this default.
Fixes#2036
The Qt UI continuously redrawing prevents libdecor-gtk's glib dispatch loop
from ever returning since it constantly posts new messages to draw again.
The result is that Moonlight randomly hangs (with the spinner still animating)
at the "Starting app..." phase of connection establishment and never proceeds
until the livelock is broken by loss of focus, hiding the window, or similar.
For posterity, the hanging stack:

We should be using the EGL renderer's colorspace and color range
rather than the backend renderer's for fallbacks. The former is
what actually gets passed to the host PC during stream init.
Huge thanks to @oliverlj for identifying this longstanding bug.
This is likely responsible for many different issues with the DRM renderer randomly failing.
