What to build

Wire the MidRollRule (already modeled on ProgrammingBlock) into the schedule engine. When a program item is longer than the configured break interval, split it into segments with interstitial slots at break points.

Break point selection: if the MediaItem has chapters and prefer_chapters is true, use chapter boundaries as break points. Otherwise, use the fallback_interval_mins to break at fixed intervals. Fill break slots with interstitials from the library matching the rule's pool_filter, up to break_duration_secs total.

The split program segments should appear as separate ScheduledSlots with adjusted start/end times. Each break slot contains interstitial content. The Playout Service will later inject SCTE-35 markers at these boundaries.

Acceptance criteria

A 2-hour movie in a block with MidRollRule (interval 30min, break 2min) produces multiple program segments + break slots
When the movie has chapters and prefer_chapters is true, breaks align to chapter boundaries
When the movie has no chapters, breaks fall at fixed intervals
Break slots are filled with interstitials from the library matching pool_filter
Short items (under the break interval) are not split
Test: movie with chapters breaks at chapter points
Test: movie without chapters breaks at fixed intervals
Test: item shorter than interval is not split
