- DB migration v32: task_assignments and event_assignments join tables
with CASCADE delete; existing assigned_to data migrated automatically
- Tasks API: accepts assigned_to as array, returns assigned_users[]
with json_group_array; filter uses EXISTS on task_assignments
- Calendar API: same pattern via event_assignments; serializeEvent
includes assigned_users array
- Recurring task completion copies all assignments to the new instance
- Frontend: shared UserMultiSelect component with avatar stack display
(renderAvatarStack, renderUserMultiSelect, getSelectedUserIds,
bindUserMultiSelect); tasks.js and calendar.js use it in modals
and card/agenda views
- CSS: user-multi-select.css with avatar-stack and user-ms classes
- 14 new tests covering CRUD, JSON aggregation, EXISTS filter,
and CASCADE behavior for both task and event assignments
Closes#125
