fix: correct import path in test_cache.py

[31413Hao]

Problem

Running pytest tests/ after pip install -e . fails with:

ModuleNotFoundError: No module named 'src'

This is because test_cache.py uses from src.gitfetch.cache import CacheManager, but after editable install, the package name is gitfetch, not src.gitfetch.

Solution

Change the import from:

from src.gitfetch.cache import CacheManager

to:

from gitfetch.cache import CacheManager

Testing

After this fix, all 4 tests in test_cache.py pass:

$ pytest tests/test_cache.py -v
tests/test_cache.py::TestCacheManager::test_cache_expiry PASSED
tests/test_cache.py::TestCacheManager::test_stale_cache_retrieval PASSED
tests/test_cache.py::TestCacheManager::test_cache_minutes_parameter PASSED
tests/test_cache.py::TestCacheManager::test_cache_timestamp_update PASSED

============================== 4 passed ==============================
