Release v7.47.0

Changed

• Renaming a Screenplay event while keeping stored events readable: pin the old stored name with id "<old name>", which ESM v16 now carries to renderers as the event's stored name. The skills cover the pin rules (PLAY0472), the end of the interim PLAY0686 caveat, and what Stage and the cratis CLI render today (#654)
• The Screenplay release baseline: run screenplay baseline admit in the release job and screenplay baseline check in CI, read the baseline through the MCP, and which event edits a baselined revision accepts; this replaces the earlier eventNeverPersisted guidance (#655)
• The standalone Screenplay tool pin and pinned language contract move to 4.153.0 (part of #655)

Fixed

• Corpus verification recognizes nested Screenplay commands such as screenplay baseline admit from the pinned contract (part of #655)
