Function CreateCFunction

bridge.c:509–546

CreateCFunction - encapsulates C function creation logic This function handles: 1. Function type validation and proxy selection 2. JS_NewCFunction2 call with proper parameters 3. Error handling Parameters match JS_NewCFunction2: ctx, name, length, cproto, magic Returns JS_EXCEPTION on any error, proper JSValue on success

// Parameters match JS_NewCFunction2: ctx, name, length, cproto, magic
// Returns JS_EXCEPTION on any error, proper JSValue on success
