feat(m1): synthesis — components + anomaly/event/missing (T1.3)
- generate_series: baseline + trend + seasonality + noise (opt heavy-tail)
- inject_anomaly: spike / level_shift / variance_change / missing_segment / drift
* non-overlapping segments (TDD caught an overlap bug) -> labels exactly
match contiguous [start,end) runs
* returns (series, point labels, segment metadata)
- couple_event: persistent per-channel step at t + event text
- add_missing: NaN drop at given rate
- tests/test_synthesis.py (14 tests, RED->GREEN; fixed overlap regression)
Exit criteria: seed-deterministic; labels cover segments; event step persistent.
