refactor: restructure repo for cleaner GitHub landing page

Reduce visible top-level items from 21 to 14:
- Untrack test-results/, tmp/, public symlink (added to .gitignore)
- Move agent-teams/ → docs/agent-teams/
- Move mobile-test/ → test/mobile/
- Move tools/remotion/ → scripts/remotion/
- Move eslint.config.js, vitest.config.ts → config/

All path references updated across CLAUDE.md, package.json,
.prettierignore, vitest configs, and capture scripts.
