Describe the Bug

Navigation features related to pytest fixtures like the "Go to Definition" and "Go to References" are not supported. I would expect to be able to jump to the definition from the fixture in the test parameters, as well as getting all usages listed when doing "Go to references" on the fixture implementation.

These are special cases since the fixtures are not called directly but resolved via name-based dependency injection by pytest during collection. Currently they are treated as common functions and parameters.

Tested on:
Vscode: 1.106.3
Pyrefly Extension: 0.46.0
