Summary

Issue #6 — Improve RAG accuracy: tuned ranking weights (similarity 50%, source type 20%, recency 15%, depth 15%), removed wasted resolution factor, added source deduplication (max 3 chunks/source), extended recency half-life to 90 days, added 15% chunk overlap, fetch 3x candidates for ranking

Issue #7 — Improve oracle prompt templates: added chain-of-thought reasoning, structured citation format, "I don't know" fallback, few-shot example, enriched commit citations with short SHA

Issue #5 — Write compelling README: hero section, problem statement with metrics, architecture diagram, example Q&A, tech stack, quick start guide

Closes #5, #6, #7

Test plan

Deploy query-service and verify /search returns diverse, well-ranked results

Verify chunk overlap works correctly for long text (ingestion-flow)

Trigger Oracle via MR comment and confirm chain-of-thought reasoning in answer

Confirm citations include MR/Issue references and commit SHAs

Review README renders correctly on GitLab
