All-day events returned for two days when querying with date objects

[fzellini]

When calling events with start = end = date objects, all-day events are returned for two days instead of one.
I believe the issue is in icalparser.py, around line 443.
Current logic includes events when:
e.end >= f and e.start <= t
This causes an all-day event to be included on the following day as well.

Example
I have a daily all-day event for 2025-12-12:
e.start = 2025-12-12 00:00
e.end = 2025-12-13 00:00

When querying events for 2025-12-13, the event is still returned because:
e.end >= f # True (2025-12-13 00:00 >= 2025-12-13 00:00)

This results in the event being reported for both Dec 12 and Dec 13, even though it should only appear on Dec 12.
Proposed fix

Exclude all-day events whose end exactly matches the query start:

elif e.end >= f and e.start <= t and is_not_exception(e.start):
if not (e.all_day and e.end == f):
found.append(e)

With this change, all-day events are correctly reported only for the intended day.
