fix: pluginList filter

TL;DR: Prevent ignored files from being re-included via subdirectory traversal

Hi, and thank you so much for this awesome project! ❤️ I really appreciate the work you’ve put into making it clean and useful.

While integrating the plugin system, I noticed a small issue in the file filtering logic: Even if a file is correctly ignored via .swiftbarignore rules (e.g., test2/test2.sh), it could still be re-included later when traversing its parent directory (test2/) recursively. This behavior breaks the expectation that once a file is ignored, it should never be returned.

🔧 What this PR fixes

This PR ensures that ignored files remain excluded, even when walking through directories that themselves are not ignored. It does so by reapplying the ignore patterns during recursive traversal of filteredDirs.

✅ Example

Given a directory (can be download at test_filter.zip):

test1.sh
test2/
  └── test2.sh

With .swiftbarignore content:

test2/test2.sh

Previously: test2/test2.sh was still returned. After this PR: only test1.sh is returned, as expected.

Let me know if you’d like any changes or test cases added — happy to iterate! Thanks again for your fantastic work! 🚀

@superpung I'm not sure what happened here, but basically

1. I missed this PR
2. The changes you're suggesting are already in main

Looks like I somehow forgot to credit you? 😶
