Function cache_location 

pub fn cache_location(workspace: &Workspace) -> PathBuf

Where the cache is: as in Nx, NX_CACHE_DIRECTORY, then nx.json cacheDirectory, then the default runner’s tasksRunnerOptions.default.options.cacheDirectory, relative to the workspace root, with qk’s entries in qk/v1 inside so they never mix with Nx’s; otherwise cache_directory, shared by the repository’s worktrees.
