v1 dropped any overlay video or audio clip whose start fell outside a chunk's
window, so a multi-slide background video — or looping background music — silently
vanished from every chunk after the one it started in, diverging from a full render.
v2 includes any clip that OVERLAPS the window and seeks into clips that began
earlier so they resume mid-clip at the seam instead of restarting:
- _extract_video_events: overlap test + VideoEvent.skip_override (loop-aware phase);
the input -ss also seeks the clip's embedded audio (tvaud).
- _extract_audio_events: overlap test + AudioEvent.src_offset (loop phase / linear);
renderer honors it in the loop-with-pauses, standard-loop, and one-shot paths.
- _chunk_boundary_span_warnings downgraded from "will be dropped" to informational.
Full (non-chunked) render is unchanged: time_range=None leaves skip_override/
src_offset at defaults. Slides already used overlap; outros are last-chunk-only.
Plan-level checks in tests/test_chunking_v2.py (all green). Remaining gate: render-
seam frame/phase validation on the rig; crossfade-loop audio seek deferred. See
docs/chunking_v2.md.
