This PR fixes a logic bug in CallSiteToString() where a suffix comparison using indexOf may return -1, which can cause incorrect [as methodName] aliases to be appended.

For example, when functionName = "doSomething" and methodName = "customMethod", the current logic evaluates -1 != 4 and appends an alias even though the method name is not present.

This change ensures indexOf returns a valid position before comparing suffix. Alternatively, String.prototype.endsWith() is used for clarity where supported.
