/*
* FPV RX — how frequency search and lock work
*
* 1. Power metric: We use channelized power (baseband IQ magnitude² in the
* capture bandwidth), not raw RF RSSI. Stats come from ChannelStatsCollector
* over filtered IQ, so we see power in the tuned channel, not wideband.
* 1. Power metric: We use channelized power that portapack RSSI algo included.
*
* 2. Scanning: We step through FPV bands/channels (A/B/E/F/R, 8 ch each). When
* power on the current channel exceeds the detect threshold, we enter
* "Candidate" and run verification — we do not lock on a single peak.
* "Candidate" and run verification - with some edge detecting algo.
*
* 3. Verification (making sure the drone is on that freq):
* - Multiple samples: verify_hits / verify_misses over several updates.
