Remove redundant exception handlers.

Since map_error_to_http_exception internally evaluates the exception type and processes both AgentError and generic Exception types, catching them separately to perform identical logic is unnecessary.

♻️ Proposed refactor
-    except AgentError as e:
-        raise map_error_to_http_exception(e)
     except Exception as e:
         raise map_error_to_http_exception(e)

HTTPException; remove its broad map_error_to_http_exception handling and let
those HTTP exceptions propagate unchanged.

6-17: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Simplify fallback logic and remove dead code.

Since this mapper is called after catching Exception (e.g., in sessions()), exc will always be an instance of Exception. The else block mapping to "Unknown Error" is unreachable.

You can simplify the function by removing the redundant isinstance check and the dead else block, leaving a clean, unconditional fallback for unexpected errors.

♻️ Proposed refactor
 def map_error_to_http_exception(exc):
     # 1. Add passthrough for HTTPException to prevent overriding status codes
     if isinstance(exc, HTTPException):
         return exc
     # 2. Handle domain-specific errors
     if isinstance(exc, AgentError):
         return HTTPException(status_code=status.HTTP_409_CONFLICT, detail=str(exc))
-    # 3. Fallback for unexpected failures
-    elif isinstance(exc, Exception):
-        return HTTPException(status_code=status.HTTP_500_INTERNAL_SERVER_ERROR, detail="Internal Server Error")
-    else:
-        return HTTPException(status_code=status.HTTP_500_INTERNAL_SERVER_ERROR, detail="Unknown Error")
+    # 3. Fallback for unexpected failures
+    return HTTPException(status_code=status.HTTP_500_INTERNAL_SERVER_ERROR, detail="Internal Server Error")
