Wire hyperscript activation into browser boot pipeline

- orchestration.sx: add hs-boot-subtree! call to process-elements
- integration.sx: remove load-library! calls (browser loads via manifest)
- sx_vm.ml: add __resolve-symbol hook to OP_GLOBAL_GET for lazy loading
- compile-modules.js: add HS modules as lazy_deps in manifest

HS compilation works in browser (tokenize→parse→compile verified).
Activation pipeline partially working — hs-activate! needs debugging
(dom-get-data/dom-set-data interaction with WASM host-get on functions).
