[Wiki Compiler] Agent to synthesize Qdrant hits into structured Markdown notes

[jordanpartridge]

Problem

Current Qdrant RAG re-derives knowledge per query (like fragmented tools in Nate O'Brien video: https://youtu.be/dxq7WtWxi44).

Solution

Build a WikiCompilerAgent (or tool):

• Input: Qdrant hits from searchableCollections() (multi-coll semantic search)
• Output: Compiled Markdown note with sections (summary, key facts, sources w/ vector links)
• Store in new wiki_notes Qdrant collection or Markdown files (Obsidian-compatible)
• Trigger: on-demand via CLI/tool, or auto on high-relevance new knowledge ingest

AC

• Handles contradictions (flag w/ diff)
• Links back to source vectors
• Evolves notes on re-run
