pocopine-core — client-side reactive runtime.
Pure compiled-views runtime (RFC-058 Phase 6.5). Every .poco
template lifts via #[component] into a static template plan;
mounting walks that plan instead of scanning the DOM for pp-*
directives. Reactivity is implemented against a real
js_sys::Proxy so get/set traps match Alpine-style semantics
for dependency tracking; signals, computed values, and watchers
compose with the same engine via a synthetic
[reactive::SIGNAL_SCOPE].
