Adds the passive RSSI hot/cold finder and user-initiated GATT play-sound (AirTag/DULT/Find My; Samsung/Tile point to their apps). README notes ringing as the one active operation.

- detect/PresenceEngine.kt: identity-agnostic streaming detector for key-rotating clones (novel-churn gate, seamless-handover chain, co-movement gate, coherence). Full design in docs/detection-rotation-clone.md.
- Wired into ScanService as a parallel signal; CONFIRMED verdict raises a distinct rotating-tracker alert (softer tiers stay silent pending real-capture validation).
- PresenceEngineTest: synthetic clone (moving -> CONFIRMED), stationary clone (gated), single real tracker + far-ambient (CLEAR).
- CI now runs :app:testDebugUnitTest so the engine has behavioural verification, not just a compile check.

paper/vigil.md: per-ecosystem detection methodology (Apple/FMDN/Samsung/Tile/DULT) and the rotation-clone presence engine (identity-agnostic detection, the rotation-rate squeeze, FP analysis, honest floor). Draft working paper accompanying the reference implementation.
