Research direction

Start by locating the JSValue enum, JSString, JSBridgeClass, StringProtocol, and JavaScriptObjectRef definitions in JavaScriptKit. Trace how string values are currently copied and re-encoded, then determine the scope needed for a JSString-backed representation. Done means String values use the proposed representation without the existing copying and re-encoding overhead.

Written by the indexing model from the issue text.

Description

-    case string(String)
+    case string(JSString)
}

+ class JSString: JSBridgeClass, StringProtocol {
+    internal let id: JavaScriptObjectRef
+    ...
+ }
