feat: add @tpmjs/create-basic-tools CLI generator

- Interactive CLI generator for scaffolding TPMJS tool packages
- Generates packages with minimum 2 tools (ideally 2-3)
- Zod 4 schemas - uses Zod directly (not jsonSchema wrapper)
- One file per tool in src/tools/<toolName>.ts
- TPMJS validated against official schemas from @tpmjs/types
- Complete package generation ready to publish to npm
- Works both standalone and in monorepo packages/ folders
