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.
