refactor(plugin-a11y): restructure to app/ + src/{node,client-script} + playgrounds/

Establish the canonical built-in plugin layout on a11y:
- app/ holds the framework SPA (was src/spa), built by Vite into the --assets package
- src/node/ holds all node-side code (definition, setup, cli, rpc)
- src/client-script/ holds both browser scripts (client runtime + page script), built by tsdown
- playgrounds/ holds the same-origin playground host (was demo/)
- dev serves the panel under its base path with HMR + a live node-side bridge
- play builds then boots the playground against the built plugin
- rename the ./client export subpath to ./client-script
