This patch improves clear cache functionality by:
- Reducing kingfisher cache removal to one command (The two commands running async was leading to warning logs. One was a subset of the other)
- Removing all files under the cache folder where not currently used by other processes
Full Functionality test
-----------------------
PASS
Device: iPhone 13 mini (Physical device)
iOS: 17.0.3
Damus: This commit
Special remarks:
- I had to locally delete other unit tests to be able to build the test target
- Unit test run on an earlier version of the patch. Test coverage should still apply since this newer patch is a subset of the previous.
Setup: Run Damus with debugger connection to Xcode
Test steps:
1. Follow multiple active accounts (Skip if local Damus is already filled up with GBs of data)
2. Scroll down on the feed for a couple of minutes (or until you have seen at least a few images, a few videos, and link previews) (Skip if local Damus is filled up with GBs of data)
3. In Xcode, download a storage container (Window > Devices and Simulators > Select the device > Select Damus > click on (...) > Download container)
- Note: Even though you see the file, it does not download instantly. Monitor the file size until it roughly reaches the size reported in iOS storage settings, as the download may still be in progress. This may take a few minutes in some cases.
- Also take note of storage usage in iOS settings
4. Open the app data package using terminal
5. Run `du -h . | sort -hr`
6. Clear cache and check logs. Logs should indicate the caches being cleared, and there should be no storage-related warning/error logs. PASS
7. Download a new storage container. Remember to wait until it completes download.
8. Run `du -h . | sort -hr` on it.
9. Compare. There should be much less data. Also check iOS settings storage usage. PASS
10. Go back to the home feed and start scrolling, browsing, follow some other people, etc. Look at your own profile as well. Everything should appear to be working as expected with no crashes or important data loss
11. Check bookmarks are still present. PASS
12. Run `DamusCacheManagerTests`. Should pass. PASS* (*See special remarks)
Results:
- Storage usage goes from 3.9GB to 394.7MB
- Damus works as normal after clearing cache, and after restarting the app as well. It becomes slower for a moment, but after a bit it loads as normal again.
- No warning or error logs pertaining to clearing cache
- Unit test passes

Biggest storage used remaining is in the Documents folder where NostrDB is stored. However, we do not want to clear NostrDB, so this is expected behavior.
