Release v7.25.0

Added

• Corpus verification compiles every screenplay example in the skills with the pinned standalone Screenplay tool. Complete models must compile with no diagnostics, examples that demonstrate a diagnostic must produce exactly the declared codes, models with specifications run screenplay test, and fragments compile inside a declared parent or are listed as skipped. A skill opts in with a play-compiles assertion in its verification.json. (#416)
• CI installs the Screenplay version pinned in the toolchain skill and requires the check; locally a missing tool is reported as skipped, never as passed, and a different tool version fails. (#416)
