feat(editor-toolbar): "Record simulation" overflow item (replay v2)

Sixth overflow-menu item, Pro-badged. Dispatches
velxio-pro-replay-record-toggle (projectId in detail) which the pro
overlay handles — plan check, board-type check, start/stop the
recorder. OSS build has no listener → silent no-op.
