gh pr create --title "fix: resolve deprecation warnings, typo, and xpassed tests" --body-file - <<'EOF'

Summary

This PR addresses three minor issues in the codebase: Python 3.13+ deprecation warnings, a typo in documentation, and tests marked as xfail that are now passing.

Changes Made

1. Fix Python 3.13+ Deprecation Warnings (tests/unit/test_marks.py)

• Issue: ast.Dict.init deprecated the ctx parameter in Python 3.13+
• Fix: Removed ctx=ast.Load() from 4 ast.Dict() constructor calls
• Lines changed: 156, 170, 179, 190

2. Fix Typo in MQTT Client (tavern/_plugins/mqtt/client.py)

• Issue: Docstring contained typo "faull" instead of "full"
• Fix: Corrected to "If the queue is full trigger an error in main thread somehow"
• Line: 300

3. Fix xpassed Tests (tests/unit/test_helpers.py)

• Issue: TestPykwalifyExtension class was marked with @pytest.mark.xfail but tests are now passing
• Fix: Removed @pytest.mark.xfail decorator
• Line: 275
