"""Phase 12 sites 1, 2+3, 5, 6: Pattern 1 (catch + raise from X) fixes.

Site 1 (_load_credentials):
  except FileNotFoundError:
      raise FileNotFoundError(f"...")
  Missing `from e`; per styleguide Pattern 1 requires `raise X from e`.

Sites 2+3 (_default_send):
  if not res.ok:
      if res.errors and res.errors[0].original:
          raise res.errors[0].original  # site 2
      raise RuntimeError(res.errors[0].message ...)  # site 3
  Missing `from None`; exception comes from a Result, not a local except.

Site 5 (_send inside _send_gemini_cli):
  if not send_result.ok:
      raise cast(Exception, send_result.errors[0].original)
  Missing `from None`.

Site 6 (_dashscope_call):
  if getattr(resp, "status_code", 200) != 200:
      raise classify_dashscope_error(...)
  Missing `from None`.
