feat: document routing for relevant context selection#10
Merged
Conversation
Instead of sending all document summaries to the LLM on every query, a lightweight routing step now selects 1-3 relevant documents first. This reduces context noise, improves answer quality, and fixes conversation memory by freeing context window space for chat history. Also increases session history limit from 6 to 10 messages.

Tests cover: - _extract_first_summary: truncation, fallbacks, edge cases (7 tests) - _route_documents: exact match, bullet prefix, fuzzy match, LLM failure fallback, empty docs, conversation history, dedup, timeout (10 tests) - process_chat routing integration: context filtering, history passing, session limit (3 tests) Also fixes a bug where the router could return duplicate doc IDs when the LLM mentioned the same document name multiple times in its response.
