Introduce moli-webmcp for native form schema synthesis, complete input validation,
numeric conversion, and JSON-LD results. Preserve requested selection values in
fill intents so the renderer can apply them to current controls after author
input events.
Add native tool activity states, selector support, control helpers, and
a namespace-aware form index that includes open and closed shadow trees.
Pin the Stylo revision providing the activity pseudo-classes.
