* Fix YEARLY recurring CalDAV events only showing on DTSTART year (#170)
Recurring events with RRULE:FREQ=YEARLY only appeared in the calendar
on the year matching DTSTART, not in subsequent years. The list_events
query filtered by , which excludes
recurring events whose original dtend (e.g. 2019-07-22) falls before
the requested window (e.g. 2026).
Fix: split the query into two branches — non-recurring events still
require window overlap, but recurring events (with non-empty RRULE)
are fetched by dtstart < end_dt alone. A new helper,
_expand_rrule_occurrences(), uses dateutil.rrule to expand each
recurring event into individual occurrence dicts within the requested
date range, so YEARLY/WEEKLY/MONTHLY events render correctly across
all years.

* recurrence: compound UIDs, frontend fixes, python-dateutil req, tests
- Replace _expand_rrule_occurrences with _expand_rrule that emits stable
compound UIDs ({base_uid}::{date_or_datetime}) so the frontend can
distinguish occurrences from the same series. Non-recurring events
pass through with is_recurrence=false and series_uid=uid.
- Add _resolve_base_uid() to extract the base series UID from compound
UIDs — used by PUT/DELETE /api/calendar/events/{uid} and the
manage_calendar tool so edits/deletes always target the base row.
- Update manage_calendar tool to import and use _resolve_base_uid.
- Frontend _updateEvent / _deleteEvent: detect compound UIDs and
invalidate localStorage cache after success so stale sibling
occurrences aren't shown.
- Add python-dateutil to requirements.txt as an explicit dependency.
- Add 14 regression tests in tests/test_calendar_recurrence.py
covering _resolve_base_uid edge cases, _expand_rrule with
yearly/weekly/monthly/all-day/bad-rrule, unique UIDs, and
metadata inheritance.
- Merge upstream's cleaner SQLAlchemy or_/and_ query pattern.
* recurrence: overlapping malformed-RRULE, exclusive end, multi-day crossings
Fix three edge cases in _expand_rrule:
1. Malformed-RRULE fallback now checks window overlap. list_events
fetches recurring rows with only dtstart < end_dt, so a broken
old recurring event could appear in unrelated future windows.
Now fallback returns [] unless the base event's dtstart/dtend
actually intersect [start, end).
2. Exclusive end boundary. rule.between(start, end, inc=True) was
inclusive on end, but the route contract and non-recurring SQL
filter both use [start, end). Added occ_start >= end guard.
3. Multi-day crossings. A recurring occurrence that starts before
the window but ends inside it was missed (only occ_start was
checked). Now expands from start - duration and filters by
occ_start < end AND occ_end > start, matching non-recurring
overlap behavior.
Tests: +4 tests for these cases (18 total)
