Architecture Blueprint Generator skill: what it does and how to install it

What it does. Analyses a codebase to identify its technology stack, architectural patterns and component relationships, then produces a Project_Architecture_Blueprint.md document. The blueprint can include diagrams, implementation examples, decision records and guidance for extending the architecture.

When to use it. When documenting an existing project's architecture or creating a reference for maintaining consistency as it evolves. It can focus on a specified technology or architecture pattern, or detect them from the codebase.
