Add projects with routines, urgency tracking and health scores

Projects group recurring routines (chores included) with an append-only
snapshot table (id, version) so edits never rewrite history; completions
reference the exact snapshot. Pure metrics compute due dates, urgency
buckets (ok/due/late/veryLate) and 0-100 health scores per routine,
project, and globally. Home page lists projects; project dashboard sorts
routines most-urgent first with one-tap completion and interval parser
inputs (1d/2w/3m/1y).
