- Vegas: a live-priority pause was only lifted from inside run_frame(),
which returns before that check while paused, so the ticker never came
back until a restart. run_iteration() now resumes it (the controller
only calls it when nothing preempts Vegas); start()/stop() clear the
pause state. Iteration length is timed with the monotonic clock.
- Dim schedule: a per-day disabled day now updates the minute-gate cache,
so brightness no longer flips back to dim within each minute.
- On-demand: a second request no longer overwrites the rotation resume
index with the first request's mode.
- Render pipeline: reset() drops the prepared group and deferred queue,
and a prefetch in flight across a reset discards its result.
- Sync: stop() removes the status file (and the controller's cleanup now
calls it), standalone removes a stale one at startup, and writes use a
unique mkstemp temp file.
- render_gate.swap_releases_gil() delegates to frame_timing.
- Stale docstrings/comments corrected.

DisplayManager.offscreen() gives a thread its own canvas, so Vegas renders every plugin's ticker content on its prefetch thread instead of pausing the scroll for canvas-bound plugins on the render thread. A render gate (src/common/render_gate.py, vegas_scroll.prefetch_gate, on by default with the GIL-releasing binding) lets the prefetch thread run Python only while the render thread waits in SwapOnVSync: on hdpi, frames 2+ refreshes late fell eightfold and late frames overall from 0.90% to 0.60%. See docs/OFFSCREEN_RENDERING.md.
