Generates hierarchical AGENTS.md knowledge base files with complexity-scored subdirectory documentation.

• Discovers project structure through parallel explore agents, bash analysis, LSP codemap, and existing documentation to build a complete codebase map
• Scores directories by file count, code ratio, symbol density, and module boundaries to determine which subdirectories warrant their own AGENTS.md files
• Generates root AGENTS.md with overview, structure, conventions, and anti-patterns, then creates subdirectory files in parallel without repeating parent content
• Supports --create-new mode to regenerate from scratch and --max-depth to limit directory traversal; defaults to update mode that modifies existing files and creates new ones as needed
