aide-analyze

Analyze the codebase for a spec. Maps affected files with file:line references, grades the change's complexity (LOW/MEDIUM/HIGH) by its risk, and creates an implementation plan with TDD. Use when: analyzing the codebase for an existing task, filling in 2-analysis.md and 3-solution.md, needing an overview of affected files and API impact. Do NOT use for: creating a new task (use aide-create), implementation (use aide-implement).
