Adds the modjam package: a MeshCore-backed test station service for
Pi (IDLE + RUNNING states, cuesheet-driven), a control station REPL
for the Mac, and a UDP simulator that swaps in for the radio when
SIMULATOR=true (drops cross-config packets and a configurable
fraction of test-payload datagrams to mimic real radio loss).
docker-compose runs three sim stations + control on a bridge net.
TSV log format matches the reference traces.
Pytest suite covers protocol codec, cuesheet builder, TSV logger,
config loader, and UDP radio packet routing/loss; .forgejo/workflows
runs it on push to main and on PRs.
