* feat(engine,producer,cli): verify video comps via deferred DE init + capture p50 Closes the two biggest gaps in the first day of v0.7.38 wild data: 88% of drawElement renders (video comps initialized via probe sessions) ran with self-verification unarmed, and speedup was measurable on only 3 of 76 renders. - Deferred drawElement init: probe sessions initialize before video extraction, so they have no frame injector — ground-truth screenshots would capture black <video> boxes, and verification skipped the whole comp. DE init now stops after the gates for injector-less video comps (deInitDeferred; autoAlpha flag retracted in case no path completes it) and completeDeferredDrawElementInit finishes verification + canvas injection + worker-encode at capture time, once prepareCaptureSessionForReuse has attached the injector. Validated end-to-end: a probe-path video comp now arms 4 ground-truth frames with real video pixels (3x inf + 64.7dB) and renders drawElement verified. - capture_p50_ms: per-frame capture durations are sampled (capturePerf.frameMs; batch frames get the batch mean) and the median ships as CapturePerfSummary.p50TotalMs -> RenderPerfSummary.captureP50Ms -> render_complete capture_p50_ms. Unlike capture_avg_ms it is immune to first-frame warmup and stage-setup amortization — smoke: avg 15ms vs p50 8ms on the same render, p50 matching the measured steady-state floor. Dashboard speedup tiles can drop their frame-count floor once this ships. - video_count on render_complete: segments speedup by video-injection comps (whose per-frame gain is legitimately lower) vs pure-graphics. Canary suite 7/7; engine suite 905 passed (1 pre-existing upstream failure); tsc/oxlint/oxfmt clean.

Complete the deferred init on the sequential disk path under the same explicit-opt-in test the orchestrator clamp uses; default-on renders stay on the screenshot baseline (this path has no drain-time self-verification, per the #1998 confinement rule). Validated: video comp + PRODUCER_ENABLE_STREAMING_ENCODE=false + explicit opt-in logs "(deferred drawElement init)" completion on capture_disk and renders correct video pixels.
