fix(ci): Initialize test projects before running workflow tests

Test projects need to be initialized with 'ff init' to create
.fuzzforge directories before workflows can run. Added initialization
steps to all workflow test jobs:
- Fast workflow tests
- Android platform tests
- Full workflow tests

This ensures projects are properly set up in CI where .fuzzforge
directories don't exist (they're in .gitignore).
