feat: configure minimal inline interactive CLI as absolute default and resolve require import issues

- Force standard interactive CLI (Claude Code style) as the absolute default interactive entrypoint
- Route and stream general chat query responses cleanly to standard out under the user prompt
- Support /add and dot-prefixed shortcuts completely in the default CLI mode
- Launch full alternate-screen swarm TUI dashboard on demand via /swarm or .swarm
- Replace CJS require("node:fs") with standard ESM node imports to prevent runtime compile/crash issues depending on compilation context
