feat: add knowledge-silo command to detect team knowledge silos#76
Conversation
Analyzes git history per directory to identify areas where only one or two people have contributed. Computes silo scores using Herfindahl concentration index and contributor count, then ranks directories by risk level (critical/high/medium/low). Includes markdown and JSON output, optional DB persistence via --save, configurable directory depth and minimum commit thresholds.
