Handles the subset used in JSCalendar: P[nW][nD][T[nH][nM][nS]]. Does not handle months or years (JSCalendar uses recurrenceRules for those). Examples: "PT1H30M" → timedelta(hours=1, minutes=30) "P1DT2H" → timedelta(days=1, hours=2) "P0D" → timedelta(0) "-PT15M" → timedelta(seconds=-900) Args: duration_str: ISO 8601 duration string.
