🎨 Add Rich CLI formatting to transformer milestone 05

Browse Source 
Updates to vaswani_shakespeare.py:
- Add Rich console, Panel, Table, and box imports
- Replace all print() statements with console.print() with Rich markup
- Add beautiful Panel.fit() boxes for major sections (Act 1, Systems Analysis, Success)
- Use Rich color tags: [bold], [cyan], [green], [yellow], [dim]
- Format training progress with colored loss values
- Display generated text in green
- Add architectural visualization with Rich panels

Updates to transformers_dev.py:
- Remove all try/except fallback implementations
- Clean imports only (no development scaffolding)
- Use proper module imports from tinytorch package

Milestone now matches the beautiful CLI pattern from cnn_digits.py
