Issue # (if applicable)

Closes #9146

Reason for this change

When bundling assets with IgnoreMode.GIT, files that should be included via negation patterns (like !*.html) are incorrectly excluded if they're inside directories that are also re-included by negation patterns. Here's an example - consider the following tree:

- index.html
- app/
    - component.js
    - index.html
    - home.html

If we use a exclude pattern of ['*', '!*.html', '!*/'], the index.html in the root and both HTML files from the app folder should be included - the app folder shouldn't be excluded, due to the !*/ pattern. Right now, only the index.html file in the root folder is included.

Description of changes

Similar to #22002, I've updated the completelyIgnores logic that's used to check if we need to skip a directory tree to include a trailing slash before verifying whether it's an ignored pattern. This makes it properly match directory-specific negation patterns like !*/ by ensuring we're checking directory paths (with trailing slashes) against directory patterns.

I've also updated the logic in fingerprint to check if we're ignoring directories or files, and call completelyIgnores or ignores accordingly.

Describe any new or updated permissions being added

None.

Description of how you validated changes

Added unit tests covering the described scenarios.
