fix(#4411): BRICK — infinite recursion in live anchor-scene window exports

Codex ship-gate (CORE). ui.js:9241 re-exported three top-level functions via
same-name wrappers (window.X = function(){ return X() }). In a classic script a
top-level `function X(){}` IS window.X, so the wrapper reassigns that global to
itself → infinite recursion → RangeError: Maximum call stack size exceeded on
every live worklog render / session reattach / snapshot-restore path (send,
sessions.js:1264/1375/570). Replace with direct assignments. JS-only brick the
pytest suite can't catch (no JS execution) — confirmed by classic-script semantics
+ will verify live in-browser. Co-authored-by: franksong2702 <franksong2702@users.noreply.github.com>
