Function resolve_path_with_discovery

src/config.rs:705–714

Like [`resolve_path`], but when `path` is `None` it walks up from `cwd` to find the nearest initialised `TraceDecay` project before falling back to `cwd` itself. Used by `serve`, `sync`, and `status`. NOT used by `init` (which must create a fresh project at the target directory).

(path: Option<String>)

/// Used by `serve`, `sync`, and `status`. NOT used by `init` (which must
/// create a fresh project at the target directory).

        PathBuf::from(p)
    } else {

        discover_project_root(&cwd)
            .or_else(|| crate::worktree::git_worktree_root(&cwd))
            .unwrap_or(cwd)
    }
