Pull Request Overview

This PR refactors test utilities from an ad-hoc #[path] import pattern to a proper module structure. The test helpers are moved from tests/test_utils.rs to src/test_utils/mod.rs and exposed as a public module, allowing tests and benchmarks to import them via standard module paths.

Key changes:

• Moved test utilities from tests/test_utils.rs to src/test_utils/mod.rs as a public module
• Updated all tests and benchmarks to use adblock::test_utils instead of local #[path] imports
• Reorganized flatbuffer generated code into src/flatbuffers/mod.rs for better module structure
