feat(seed): add seed script + fix Tailwind scanning adjacent projects

- scripts/seed.ts: inserts one complete test client with 3 phases,
  6 tasks, 4 deliverables, 2 payments, 2 documents, 2 notes; prints
  shareable URL to console
- globals.css: add @source not directives to exclude .01_projects/
  and .claude/ — Tailwind v4 was scanning the SparklingOrbit .venv
  Python files and generating invalid CSS class [-:|] from a regex
  pattern in a markdown-it table parser, causing dev server 500s
