Discover data-slhx-on event names from hemplate Surface inputs and emit generated events modules plus symbol rows without adding runtime trigger semantics.

Emit handle_param facts for handled data-* attributes and reject handlers that omit generated param arguments. Cover the generated param boundary with unit and compile-fail tests.

Emit handle-form facts from slhx-build and have #[slhx::handler] reject generated form handlers that do not accept slhx::Form<_>. Cover the boundary with compile-fail fixtures.
