Release v7.107.0

Changed

• The Screenplay skills cover key <property> is event source on a single-property source events from capture. The skills explain what it promises about the producer's stream, how a fixture's for must match the key, and the PLAY0809 error for any other capture. They also cover ESM v33 and include an inbound translation example that uses the marker. (#891)
• The corpus pins the Screenplay tool and its published contract to 4.244.0, so examples using event-source capture keys compile. (#891)
