Prevent api_key authentication mistake with runtime validation
Add runtime validation to prevent users from accidentally using the wrong authentication parameter. Python now validates configuration and raises a clear ValueError with help article link if api_key is attempted instead of access_token. Changes: - Add safe_config.py with api_key validation - Override Configuration import to use safe wrapper - Preserve custom files during SDK regeneration - Update README to show only access_token usage - Replace all api_key examples with access_token Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

### Authentication
39+
40+
**Important:** The Linkbreakers API uses Bearer token authentication. The SDK's `Configuration` class is designed to only accept the `access_token` parameter:
41+
42+
```python
43+
# ✅ CORRECT - Uses Bearer token authentication
44+
configuration = Configuration(
45+
access_token='your-workspace-token',
46+
host='https://api.linkbreakers.com'
47+
)
48+
49+
# ❌ ERROR - Will raise ValueError
50+
configuration = Configuration(
51+
api_key={'ApiKeyAuth': 'your-token'} # This will raise an error!
52+
)
53+
```
54+
55+
The SDK prevents you from accidentally using the wrong authentication method and will raise a clear error message with a link to the help documentation.
56+
57+
Get your workspace API token from the [Linkbreakers dashboard](https://app.linkbreakers.com/settings/api).
