• Knowledge Graph: Ingests files and authors over time, building an explorable relationship graph to query the history of files and authors.
• AI-Powered PR Descriptions: Generates descriptions programmatically by fetching contextually similar historical PRs locally via embeddings.
• Stale PR Detection: Flags old and inactive PRs based on customizable thresholds and suggests actions (close, merge, ping reviewers).

• Express API Endpoint Expansion: Added /api/rules/evaluate, /api/graph/query, /api/graph/history, /api/describe, and /api/stale.

• Infra (ESM Support): Added exports map to package.json for proper ./server and ./bot submodule resolution.
• Infra (Dependencies): Moved heavy dependencies (express, cors, @actions/*) to optional peerDependencies to drastically reduce package size for library consumers.
