Full-stack meteor scatter monitoring mode that captures IQ data from
an RTL-SDR, computes FFT waterfall frames via WebSocket, and runs a
real-time detection engine to identify transient VHF reflections from
meteor ionization trails (e.g. GRAVES radar at 143.050 MHz).
Backend: MeteorDetector with EMA noise floor, SNR threshold state
machine (IDLE/DETECTING/ACTIVE/COOLDOWN), hysteresis, and CSV/JSON
export. WebSocket at /ws/meteor for binary waterfall frames, SSE at
/meteor/stream for detection events and stats.
Frontend: spectrum + waterfall + timeline canvases, event table with
SNR/duration/confidence, stats strip, turbo colour LUT. Uses shared
SDR device selection panel with conflict tracking.
