fix: exit agent loop when all features pass

Previously, the autonomous agent would continue running indefinitely
even after all features passed verification. The agent would enter a
verification loop, repeatedly checking 'All features are passing!'
without ever exiting.

This fix detects the completion message from feature_get_next() and
gracefully exits the main loop with a victory banner, preventing
unnecessary API calls and resource consumption.

Fixes infinite loop when project reaches 100% completion.
