WrappedFileHandler

Result of TranslationFormats.wrap():

• handler is the wrapped file handler that adds alternate-format lookups.
• lastError() returns the most recent converter error captured during this wrap's lifetime (or null). Caller reads after dispatch completes.

Defined as a class (not a typedef) because Haxe Lua wraps anonymous-struct function fields in function(_, ...) return underlying(...) end (the _ eats an implicit self arg), which breaks direct function-style invocation. Class fields don't get that treatment.
