ChuckandClaude Opus 5.5 c43c10bd78 fix(vegas): keep the sub-pixel frame interval #637 removed as dead code
On main, RenderPipeline._frame_interval was set and never read, so #637
dropped it. Here the frame_interval property reads it for the sub-pixel
path (the crisp path solves its own), so the merge brings it back, with a
comment saying who reads it. #637's new coordinator test drives a
MagicMock pipeline, which this branch's pacing reads frame_interval and
target_fps from; give the mock real ones.

"""run_iteration() does no per-iteration static-mode bookkeeping.
Every iteration used to rebuild a set of STATIC-mode plugins -- asking each
plugin for its display mode and logging the result at INFO -- that nothing
ever read. The static pause is driven by _check_static_plugin_trigger(), which
looks at the next segment, not at that set.
