Release v7.122.2

Fixed

• Stage and Screenplay key guidance now says that STAGE-ESM-048 refuses composite read-model keys with a decimal part, whether a Decimal primitive or a concept over Decimal. It explains why: a replay can split 1.0 and 1.00 into two instances. It also says when the refusal lifts. (#952)
• Guarded-interaction guidance now teaches that on change accepts alternatives, the same way click, double click and select do. It uses the current PLAY0560 wording and keeps the opaque where exemption for change, with a kanban example. (#951)
