- Add inline TODO comment in runCommand.ts about standardising
replication failure cause identification logic.
- Add test-sync-locked-remote-linux.sh that verifies:
1. sync succeeds when the remote milestone is not locked.
2. sync fails with an actionable error when the remote milestone
has locked=true and accepted_nodes is empty.
- Fixed flaky timing issues in P2P synchronisation.
- Fixed more binary file handling issues in CLI.
### Tests
- Rewrite P2P end-to-end tests to use the CLI as host.
