feat(#55): Integrate Phase 1 RAG Upgrade into Hybrid Resume Generator

[BPMSoftwareSolutions]

Summary

This PR completes the integration of Phase 1 RAG Upgrade capabilities into the hybrid resume generator pipeline across CLI, Web API, and Web UI.

Changes

Phase 1: CLI Enhancement (generate_hybrid_resume.py)

• Added RAG support with new CLI flags:
  • --jd: Path to job description
  • --use-rag: Enable RAG-based retrieval
  • --use-llm-rewriting: Enable LLM-powered rewriting (requires RAG)
  • --show-rag-context: Display RAG context in output
  • --vector-store: Path to FAISS vector store
• Integrated RAG context retrieval and LLM rewriting into resume generation pipeline
• Added validation to ensure RAG requires JD and LLM rewriting requires RAG

Phase 2: Web API Enhancement (src/api/app.py)

• Added three new RAG endpoints:
  • POST /api/rag/retrieve: Retrieve relevant experiences using semantic search
  • POST /api/rag/rewrite: Rewrite bullets with LLM and evidence constraints
  • POST /api/rag/index: Trigger re-indexing of vector store
• Enhanced POST /api/resumes/<resume_id>/tailor endpoint:
  • Added use_rag and use_llm_rewriting parameters
  • Integrated RAG context retrieval when enabled
  • Returns RAG context summary in response

Phase 3: Web UI Enhancement (src/web/dashboard.html & dashboard.js)

• Enhanced tailor modal with RAG options:
  • Checkbox for "Use RAG Retrieval" with semantic search explanation
  • Checkbox for "Use LLM Rewriting" (dependent on RAG, disabled by default)
  • Info box explaining RAG and LLM rewriting benefits
• Updated dashboard.js:
  • Added event listeners for RAG checkbox state management
  • Enhanced tailor function to include RAG options in API request
  • Added loading indicator during tailoring
  • Display RAG metrics in success message

Phase 4: Demo & Documentation

• Updated demo_rag_with_pelotech.py:
  • Added demo_hybrid_resume_generation() function
  • Included examples of RAG-enhanced HTML generation
  • Updated success message and next steps

Testing

• All 421 existing tests pass
• No new test failures introduced
• RAG integration maintains backward compatibility
