Expand orchestrator workflow with chat UI and design system - #10

Summary

• normalise project file index loading and saving to always include folder metadata and stable ordering
• tighten agent validation by checking section completeness, surfacing issues, and improving status output formatting
• fix the generated CI workflow indentation via dedented YAML content for merge-friendly scaffolding
• implement the chat-only orchestrator entrypoint with async project probing, gated approvals, and cost reporting
• add UI designer assets, design tokens, and a frontend scaffold that consumes the shared token library
• seed backend health endpoints, environment templates, and documentation for orchestrator mode
• surface pre-fetched hash samples when prompting to reuse an existing project so conflicts can be spotted early

Testing

• python -m compileall src ui
