…ST API + JS API + CLI, add unit tests, add example config files

- Add clone-project.mjs tool for cloning projects between environments
  - Supports config files, verbose mode, and skip-files option
  - Silent by default, outputs only destination ID to stdout
  - Verbose output goes to stderr for proper piping
- Add REST API methods to protobi-rest-api.js:
  - getDataset() - retrieve dataset metadata
  - getDataTables() - list data tables
  - downloadData() - download raw CSV data
  - uploadCsvText() - upload raw CSV data
- Fix all fetch() calls to use nodeFetch() for SSL certificate support
- Remove debug console.log statements
- Use only API routes (/api/v3/**), not web routes (/v3/**)
- Update dependencies (chalk, etc.)

- Replace custom parseArgs with commander for better CLI parsing
- Remove chalk (not worth the dependency for colored output)
- Remove unused dependencies: fs-extra, inquirer, lodash.merge, ora
- Move commander to devDependencies (only used by tools)
- Final dependencies: 3 core (csv, form-data, node-fetch) + 5 dev
- Removed 56 packages from node_modules
