fix: additional fixes for http error handling and path resolution

- http-client.ts: Limit error response data collection to 10KB and add error handlers
- RoadmapGenerationProgress.tsx, GenerationProgressScreen.tsx: Allow onStop to return Promise<void>
- insights_runner.py: Fix path resolution and load .env from auto-claude directory
