v0.26.0 — Calendar: month view of all tasks + bloom/harvest windows

New /calendar page merges every Task (garden, home, equipment, animals)
into one month grid, color-coded by category, with a click-a-day detail
panel and inline Done (reuses /api/tasks/[id]/complete). Recurring tasks
project every occurrence in view via the new occurrencesInRange in
src/lib/tasks/schedule.ts (first tests for that module — 12, including
month-end clamping). Season chips per month come from PlantType
bloom/harvest windows via src/lib/garden/season.ts (monthInWindow,
year-wrap aware). Nav gains a Calendar item.
