[client] scheduler: qualify presentation feedback

Browse Source 
Track cadence, interruption, and calibration wake reasons independently
across X11 and Wayland. Feed phase correction back only when a pure
cadence wake renders the exact frame that was queued at that wake.

Propagate EGL swap results through the display-server boundary. Reject
failed presentations and keep pending Wayland HDR descriptions inactive
until the preceding surface commit succeeds.
