v0.11.2

Changed

• Raise the djangorestframework-services floor from >=0.21.1 to >=0.24.1
  (kept <0.25) so the MCP server always dispatches through the two DRF-parity
  fixes shipped in drf-services 0.24.1: SelectorSpec.filter_set now validates
  and rejects an invalid filter value (a 400/ValidationError, not a silent
  unfiltered result), and the input_data merge no longer corrupts
  form-encoded request bodies. MCP tool dispatch routes filter and input
  handling through drf-services (dispatch_spec), so both fixes reach MCP
  callers with no code change here. Refreshed the pinned dependency set to
  0.24.1 at the same time.
