What's the problem?
Users working inside VSCode want to review PlanBridge content without leaving the editor. Opening PlanBridge in an external browser breaks that flow.
Proposed solution
Support targeting the VSCode built-in browser when opening PlanBridge, so the annotation UI surfaces inside the editor rather than in a separate browser window.
Additional context
Migrated from #79.
