v0.27.0 — Garden brain: zone-4b knowledge, calendar suggestions, UW citations

src/lib/garden/knowledge.ts holds hand-curated zone-4b (~May 15 frost)
knowledge for 28 crops/fruits/flowers: monthly care timing, companion
friends/foes, rotation families. Pure matchers knowledgeFor/tipsForMonth
use whole-word stem matching (tested — 'Pear' must not hit 'Pea'). The
calendar gains a "Good to do this month" list matched to owned plants,
deduped against existing task titles, with one-click Remind me → YEARLY
task via /api/v1/tasks. Plant type pages gain a "Growing in zone 4b"
card (timeline, companions, rotation). Tips cite UW Extension via site
search URLs — no fabricated article links.
