Inconsistent File Linking with @ in Nested Directories with Hyphens

Bug Description
cannot link files with @ if it's in a nested directory with a hyphen. e.g. foundation-webapp/app/components/feature-components doesn't work, while foundation-webapp/app/components/featurecomponents does work. but in another case of testing, that also didn't work. it's a bit inconsistent.

example:

➜  test tree .
.
└── foundation-webapp
    └── app
        └── components
            ├── feature-components
            │   ├── test.txt
            │   └── test.txt~
            └── featurecomponents
                └── test2.txt

running claude in this dir, writing @test leads to no auto-completions at all.
