Giuseppe Scrivano 8a26d6ba1f tests: add comprehensive tests for custom-handler.c
Add both unit tests and Python integration tests to improve coverage
for src/libcrun/custom-handler.c which is currently at 28.2% coverage.

Unit tests (tests_libcrun_custom_handler.c):
- Test handler manager creation and cleanup
- Test handler lookup by name
- Test feature tag printing
- Test handler configuration with various scenarios
- Test error paths and edge cases

Python tests (test_custom_handler.py):
- Test sandbox annotation handling
- Test non-existent handler requests
- Test --handler command line option
- Test annotation and context handler conflicts
- Test feature tag output in --version
- Test empty and invalid handler annotations
