fnox 1.5.2 (new formula)

- Added Formula/f/fnox.rb
- Improve fnox formula test with real age encryption
- Generate test age key using system age-keygen instead of hardcoded key
- Use fnox set to properly encrypt test secret before testing
- Add test for fnox get TEST_SECRET to verify decryption works
- Fix environment variable to use FNOX_AGE_KEY instead of AGE_KEY
- Provides better end-to-end validation of fnox installation
