[BUG] Extension does not handle git worktrees correctly

[RasmusRendal]

Describe the bug
When getting the .git/config, it assumes that it's in the work directory:

vscode/src/coverage/coverage.ts

Line 140 in f708fe8

const gitConfig = Uri.file(`${pathToWorkspace}/.git/config`);

If somebody like me is a fan of worktrees, they won't have a .git folder in their workspace. Instead, .git will be a text file containing something like this:

gitdir: /home/rasmus/Projects/repo/main/.git/worktrees/branch

When running the codecov extension in a linked worktree, that has such a .git file in lieu of a directory, that will result in the following error:

 Error: ENOTDIR: not a directory, open '/home/rasmus/Projects/repo/branch/.git/config'

To Reproduce
Steps to reproduce the behavior:

1. Clone a repository
2. Run git worktree add -B branch ../branch
3. Open ../branch in vscode with the codecov extension enabled

Expected behavior
The codecov extension should correctly resolve the git repository, and work as well in linked worktrees as in main worktrees.

For similar reasons, the inflexibility of the git config lookup also makes this extension break when using a multi-repository workspace in VS Code. I'm just going to dump my LLM chat as I think it has correct context into this variation of the problem:

Response:

These errors are coming from the Codecov VS Code extension trying to read your repo’s config but getting an undefined workspace URI (this commonly happens in multi‐root workspaces). You have three simple work-arounds:

1. Open the repo itself (e.g. infra) as your single root workspace so the extension can find config.
2. Upgrade (or downgrade) the Codecov extension—there’s a patch in newer versions that fixes this multi-root issue.
3. If you don’t need the in-editor decorations, disable them in your workspace settings (in settings.json):

Pick the approach that best fits your workflow.

I was able to work-around by ditching my multi-repo workspace, but this is a big hit to productivity and probably not an option for many users like myself and my team, who primarily want this for the decorators.
