Fixed mode keeps the existing behavior: next_due always advances from
the previous scheduled date, regardless of when a task is actually
completed. Floating mode instead computes the next occurrence from
the completion date of the current task, so early/late completion
shifts the whole schedule.
- task_templates gains schedule_mode ('fixed'|'floating', default
'fixed') and pending_task_id, tracking the open task spawned from a
floating template so the hourly sweep doesn't respawn duplicates
before it's resolved.
- scheduler.js: floating templates set pending_task_id instead of
advancing next_due at spawn time.
- tasks.js /resolve: floating templates recompute next_due from
completed_at once the task is marked fixed (not temporary_fix,
since that isn't really done yet); pending_task_id is always
cleared on fixed resolution so a stale flag can't wedge the
template if the mode changed mid-cycle.
- addInterval/isoDate pulled out of scheduler.js into a shared
lib/recurrence.js used by both the scheduler and the resolve route.
- Recurring.tsx: schedule mode toggle in the template form, and the
list shows "awaiting completion" instead of a stale next-due date
for floating templates with an open occurrence.
