- Fix 3 flaky TestEndToEndIntegration tests that failed with seed 3927212083: add autouse fixture to clear apps.finder.get_homebrew_casks lru_cache between tests; patch get_homebrew_casks at the handler import site in test_auto_updates_management_workflow so it cannot be poisoned by a cached real-brew call from another test. - Add tests/test_exceptions_and_error_codes.py (423 lines / ~64 cases) covering StructuredError, ErrorCode enums, create_error, category/ severity filters, and all nine VersionTrackerError subclasses with their optional context parameters.

Reviewer's GuideThis PR stabilizes flaky end-to-end tests by isolating Homebrew-related lru_cache state, expands low-level exception/error-code and finder/comparator coverage, slightly relaxes a performance test threshold, and updates configuration (aiohttp version and Black line length).

Hey - I've left some high level feedback:
- The LRU cache clearing logic is now duplicated across
TestEndToEndIntegration.clear_lru_cachesand the autouse fixture intest_finder_new_coverage.py; consider centralising this into a shared pytest fixture inconftest.pyso cache invalidation is consistent and easier to maintain across test modules. - The new async Homebrew tests in
test_finder_new_coverage.pyuse fairly deep nesting ofpatch/patch.dictcontext managers; extracting small helpers (e.g. a context manager or factory forfake_async) would make the intent clearer and the tests easier to follow.

## Overall Comments
- The LRU cache clearing logic is now duplicated across `TestEndToEndIntegration.clear_lru_caches` and the autouse fixture in `test_finder_new_coverage.py`; consider centralising this into a shared pytest fixture in `conftest.py` so cache invalidation is consistent and easier to maintain across test modules.
- The new async Homebrew tests in `test_finder_new_coverage.py` use fairly deep nesting of `patch`/`patch.dict` context managers; extracting small helpers (e.g. a context manager or factory for `fake_async`) would make the intent clearer and the tests easier to follow.Help me be more useful!

This patch target is ineffective for the workflow under test: handle_blacklist_auto_updates calls get_casks_with_auto_updates from versiontracker.handlers.auto_update_handlers, where it was imported directly at module load time. Since versiontracker_main imports handlers eagerly, patching versiontracker.homebrew.get_casks_with_auto_updates here does not replace the function actually invoked, so the test can still execute real auto-update lookup logic (including async/network-dependent paths) and remain flaky. Patch versiontracker.handlers.auto_update_handlers.get_casks_with_auto_updates instead.
Useful? React with 👍 / 👎.
