Release v7.43.0

Added

• The Screenplay model-authoring skill teaches the MCP surface for concept generation strategies: reading a concept's generation summary from screenplay_declaration_details (strategy, modifiers, entropy, collision estimate and whether it is executable), setting or removing generate through typed proposals, and the PLAY0683/PLAY0684 repairs that raise entropy or add a unique constraint. The cratis screenplay mcp bundled in CLI 3.57.0 does not have this surface yet (#645)

Changed

• The standalone Screenplay tool pin and pinned language contract move to 4.149.0 (part of #645)
