* fix: support root-params dynamic getters during static prerendering and SSR
* fix: enforce strict parameter isolation for root params in prerendering and SSR
* fix: correct parameter mapping in multi-source resolver and clean up handleSsr fallback
* fix: use dedicated standalone ALS for root-params outside of unified request context
* fix: thread root params through generated app page dispatch
Normal App Router page requests computed root params in the typed handler, but the generated RSC entry did not forward them into page dispatch. SSR then received an empty root params scope for requests that should expose root params.
Destructure and forward rootParams in the generated entry, assert that template wiring, reuse the shared root-param picker, and align the scope helper API with the existing runWith overload pattern.
