Add direct MakeTest inline learning

Expose the learnEdits protocol from direct MakeTest queries without relying on query metadata or @id. Share edit emission with qlref postprocessing while restricting direct reconciliation to safe line-comment syntax and leaving unsupported forms for verification.

Add Python and Java fixtures covering custom expected tags, foreign tags, standard tags, and missing query IDs.
