Move the previously untracked TypeScript CLI into iot-dc3 as an
independently managed module next to dc3-web:
- pnpm workspace (pnpm@11.24.0) with esbuild build approval,
package renamed to iot-dc3-cli, npm lockfile dropped
- add eslint flat config; lint now runs green after removing
unused imports/vars and adding switch-case breaks in config.ts
- document CLI conventions and commands in AGENTS.md
