chore: remove orphaned jest.config.js, raise vitest coverage to 70%

- Delete jest.config.js (no jest dependency in any package.json, was dead config)
- Vitest is the sole test runner (already used by all packages)
- Raise coverage thresholds from 50% to 70% (lines, functions, branches, statements)
