giles 6655f638b9 Optimize evaluator hot path: prototype-chain envs, imperative kwarg parsing ...

Three key optimizations to the JS evaluator platform layer:

1. envMerge uses Object.create() instead of copying all keys — O(own) vs O(all)
2. renderDomComponent/renderDomElement override: imperative kwarg/attr
   parsing replaces reduce+assoc pattern (no per-arg dict allocation)
3. callComponent/parseKeywordArgs override: same imperative pattern
   for the eval path (not just DOM rendering)

Wire format and spec semantics unchanged — these are host-level
performance overrides in the platform JS.
