Detailed Description

Single-target persistent tracker over detector blobs (pure C++20, natively tested).

States: Idle -> Tentative (candidate, must match confirm_frames in a row) -> Locked (id assigned) -> Coasting (missed; predicted forward with decaying velocity) -> Locked again with the same id, or Idle after coast_frames misses. Prediction is an alpha-beta filter (constant velocity, fixed gains). The measurement is the union of every blob overlapping the gate around the prediction, so a target split into parts stays one box. While Locked, blobs outside the gate are ignored even if larger. NOT thread-safe.
