refactor(build): migrate from setup.py to pyproject.toml with src/ layout

- Replace multiple setup.py files with unified pyproject.toml
- Implement src/ directory layout for better organization
- Create robocompcli package with shared utilities (cli_helpers, logging_helpers)
- Consolidate all dependencies and entry points in single location
- Remove obsolete setup.py files from root and subdirectories
- Update import statements across the codebase

This change modernizes the packaging system following PEP 621,
improves maintainability, and simplifies installation.

Migration guide:
- Install from root: `pip install -e .`
- Update imports: `from cli_helpers` -> `from robocompcli`
- All CLI tools now installed together
