Implement speech style toolbar live-edit refinements and whole speech show controls

- Added a new specification for the speech style toolbar live-edit, detailing immediate style application, scoped effect demonstration, and hover feedback.
- Introduced refinements to the speech style toolbar, including improved chooser sizing, exclusive stage editing during speech composition, and removal of redundant controls.
- Documented new stage controls for managing how the whole speech shows, including options for bubble arrangement, word appearance, and bubble motion.
- Created a new log file for speech padding syntax to track engine versioning.
