feat(rvcsi): rvcsi-events — window aggregation + event detectors (ADR-095 FR5)
- WindowBuffer: buffers exposable CsiFrames from one (session,source), emits a
CsiWindow on a frame-count or duration threshold; computes per-subcarrier
mean_amplitude / phase_variance and scalar motion_energy / presence_score /
quality_score; skips mixed source/session and mismatched-subcarrier frames.
- EventDetector trait + 4 state machines: PresenceDetector (hysteresis on
presence_score), MotionDetector (debounced rising/falling edges on
motion_energy), QualityDetector (SignalQualityDropped + once-per-stretch
CalibrationRequired), BaselineDriftDetector (EWMA baseline → BaselineChanged /
AnomalyDetected). Each with new()/with_config() + a public config struct.
- EventPipeline: owns a WindowBuffer + Vec<Box<dyn EventDetector>> + IdGenerator;
process_frame / flush / add_detector / recent_windows (32-window ring) /
with_defaults.
- 18 tests (incl. a 150-frame quiet/active/quiet end-to-end run via a seeded LCG
+ a determinism check). clippy-clean, forbid(unsafe_code), no heavy deps.
