Release v7.93.0

The Screenplay skills now teach five behaviors from recent Screenplay releases, and correct how they describe a query performer.

Added

• The model-authoring and streams-and-consistency skills teach renaming a composite stream-id part with propose-rename, which rewrites every part = ... mapping and keeps stored stream ids. (#796)
• Model review covers the SMELL006 modeling smell and the corrected SMELL005 count from find-modeling-smells. (#799)
• The specifications and scenario-coverage skills explain where a specification given that has no event source belongs. (#819)
• The command-surface and toolchain skills explain the PLAY0803 warning for matches patterns that can backtrack exponentially, and how to rewrite them. (#789)

Changed

• A query performer is now taught as an opaque read that the compiler reports as PLAY0270 information and leaves out of the executable model, rather than as a PLAY0268 refusal. Render emits nothing for it, so the skills list it as code to write by hand; older compilers still report PLAY0268. (#798)
