chore(dev): run CLI workspace entries from source

- use tsx for bl/kscli dev and test runners
- point local library exports to src while keeping publishConfig on dist
- switch vendored telemetry modules to .cjs for source-run compatibility
- update stress/e2e helpers and agent docs for the new source execution path
