Context

VS Code extensions with tree views often need a companion status bar item to provide at-a-glance information. The status bar should stay synchronized with tree data and update whenever the underlying data changes (file watcher events, user commands, data provider refreshes).

Patterns

Shared Data Provider Architecture

Both the tree provider and status bar should consume the same data provider instance. This ensures consistency and avoids duplicate data fetching.

const dataProvider = new SquadDataProvider(workspaceRoot);
const treeProvider = new SquadTreeProvider(dataProvider);
const statusBar = new SquadStatusBar(dataProvider);
