Improve Codebase Architecture

Scan your codebase for architectural friction and get a visual HTML report of deepening opportunities: refactors that turn shallow modules into deep ones for better testability and AI-navigability. The scan prioritises recently changed hot spots (or a direction you name), reads your glossary and ADRs, and explores where understanding one concept means bouncing between many small modules. Each candidate card shows the files involved, the problem, the proposed solution, benefits in terms of locality and leverage, a before/after diagram, and a recommendation strength, ending with a top recommendation. Pick one and the agent walks the decision tree with you.
