onContentResumeSeek

open fun onContentResumeSeek(targetSeconds: Double, breakEndSeconds: Double)

The renderer is about to seek content back to targetSeconds as its own post-break resume-seek, for a break ending at breakEndSeconds.

The orchestrator forwards this to BreakScheduler.notifyResumeSeek so the DVR seek-back re-arm does not read this backward step as a genuine user rewind and re-fire the just-completed break (PLAYG-241). Mirrors the web onContentResumeSeek callback. Default no-op for renderers that never resume-seek.
