feat: add Valentine's, Women's Day, Earth Day, Keti Koti, Diwali; per-year dates
New holiday layers wired up: Valentine's (2/14), International Women's Day (3/8),
Earth Day (4/22, renders behind the base), Keti Koti (7/1), and Diwali via a new
per-year 'dated:' table (no formula — verified dates 2026-2030, with a startup
warning when the table runs out). Updated the EU flag and wintermode art. README:
refreshed the schedule and removed host-specific references.
