Description
In Fiddle::ValueUtil#wrap_arg there is a long case-when for arg with an unreachable code path.
When arg and ty are of Array type, and ty[0] is TYPE_CHAR, there is another condition, for arg to be String at Line 101.
Even if this condition is fixed, val is undefined at Line 102 for this method.
https://github.com/ruby/fiddle/blob/04238cefed14a433f93909bd93dbe1d0a4efc47e/lib/fiddle/value.rb#L95-L106
Should Lines 100-103 be removed?

Research direction
Start in lib/fiddle/value.rb at Fiddle::ValueUtil#wrap_arg, especially lines 95-106 linked in the issue. Trace the Array and TYPE_CHAR branches to confirm the unreachable condition and undefined val, then determine whether lines 100-103 should be removed; done means the dead path is resolved without changing valid argument wrapping.
