Preserve combining marks in configured unit names.

DurationParser builds its lookup from configured keys, so मिनट can reach this code. The cleanup keeps \p{L} but removes the Hindi combining vowel mark (\p{M}), changing the captured key before exact lookup. The lookup then returns None, so this configured non-Latin unit still fails to parse. Preserve Unicode marks at this boundary:

line 134:
Update the captured-unit cleanup in DurationParser so it preserves Unicode
combining marks alongside letters before looking up the key in timeUnits. Keep
the existing removal of other characters and exact lookup behavior unchanged.
