A short topic pubkey panicked a lane worker and killed the process; keys must
now be 32 bytes and lane workers recover. Also reject non-finite radio values
before airtime, strip NULs from advert names and neighbour scopes, guard the
MQTT client pointer, and never stream a broker copy of a hearing as a repeat.
MarkSent ran after the side effects, so a broker copy on another worker could win it and be streamed as a repeat of the first hearing. It now runs before any further DB work, unconditionally so the set is warm before anyone opts in, and never for TRACE, whose path bytes are per-hop SNR.
Duplicate observations are dropped before the hub today, so a live map only sees each packet's first hearing per observer. Clients that configure includeRepeats also get later hearings whose path is new; nothing is stored, repeats skip the count query, and they are dropped first when the broadcast channel is half full.
