v2.0.0

Fixed

• except clauses using Python 2 syntax -- except ValueError, binascii.Error and except ConversionError, KeyError, AttributeError only caught the first exception type; the remaining names were silently misinterpreted as the exception variable. Fixed to tuple syntax except (A, B).
• Protected custom fields leaking across entries -- custom_protected list was initialized once before the entry loop and accumulated field names from every entry, causing later entries to incorrectly treat same-named properties as protected. Now reset per entry.
• Stubs missing runtime dependency -- Added explicit lxml>=6.0.2 dependency to pykeepass-stubs; previously only types-lxml was declared, leaving the runtime lxml import unsatisfied when the stubs package was installed standalone.
