Description
Summary
ruff server does not find settings (e.g. ruff.toml) when processing files that are not under the directory that the server command was invoked in, instead falling back to the default config.
This was tested using Sublime Text with the sublimelsp package using the following directory structure:
ruff-server-test
├── project-a
│ ├── ruff.toml
│ └── test.py
└── project-b <- ruff server invoked in this directory
├── ruff.toml
└── test.py
If the Sublime workspace is opened in project-b, and project-a/test.py is added to the workspace as a "free" file, calling textDocument/formatting causes the file to be formatted incorrectly. Debug logs including a server restart are shown below (I have isolated lines the relevant lines and added !!! at start).

If the sublime workspace is opened in the directory above (ruff-server-test), then the server detects both ruff.tomls and formats each file according to their respective configs. Not sure if this is really a bug or the intended behaviour, but (at least for me) it's common to open files that are not in the workspace - if the editor is configured to auto-format on save these files will be incorrectly formatted.
