Zamil Majdy b2eb4831bd feat(chat): improve agent generator error propagation (#11884)
## Summary
- Add helper functions in `service.py` to create standardized error
responses with `error_type` classification
- Update service functions to return error dicts instead of `None`,
preserving error details from the Agent Generator microservice
- Update `core.py` to pass through error responses properly
- Update `create_agent.py` to handle error responses with user-friendly
messages based on error type

## Error Types Now Propagated
| Error Type | Description | User Message |
|------------|-------------|--------------|
| `llm_parse_error` | LLM returned unparseable response | "The AI had
trouble understanding this request" |
| `llm_timeout` / `timeout` | Request timed out | "The request took too
long" |
| `llm_rate_limit` / `rate_limit` | Rate limited | "The service is
currently busy" |
| `validation_error` | Agent validation failed | "The generated agent
failed validation" |
| `connection_error` | Could not connect to Agent Generator | Generic
error message |
| `http_error` | HTTP error from Agent Generator | Generic error message
|
| `unknown` | Unclassified error | Generic error message |

## Motivation
This enables better debugging for issues like SECRT-1817 where
decomposition failed due to transient LLM errors but the root cause was
unclear in the logs. Now:
1. Error details from the Agent Generator microservice are preserved
2. Users get more helpful error messages based on error type
3. Debugging is easier with `error_type` in response details

## Test Plan
- [ ] Test decomposition with various error scenarios (timeout, parse
error)
- [ ] Verify user-friendly messages are shown based on error type
- [ ] Check that error details are logged properly
