Fix HS browser activation: host-get function sentinel, runtime symbol shadow, lazy dep chain

Three bugs fixed:
1. host-get in sx-platform.js: return true for function-valued properties
   so dom-get-attr/dom-set-attr guards pass (functions can't cross WASM boundary)
2. hs-runtime.sx: renamed host-get→hs-host-get and dom-query→hs-dom-query to
   stop shadowing platform natives when loaded as .sx source
3. compile-modules.js: HS dependency chain (integration→runtime→compiler→parser→tokenizer)
   so lazy loading pulls in all deps. Non-library modules load as .sx source
   for CEK env visibility.

Result: 8/8 elements activate, hs-on attaches listeners. Click handler needs
IO suspension support (VmSuspended in sx_browser.ml) to fire — next step.
