Skill UI

Implements Manus-style file-based planning to organize complex tasks, enforcing persistent markdown plan/findings/progress files, enforcing read-before-decide and write-after-action rules, and enabling session recovery after /clear.

Persistent file-based planning for multi-step AI agent work. Maintains task_plan.md, findings.md, and progress.md on disk; lifecycle hooks inject selected context. Automatic recovery reads only project planning files. Use for research or work with more than 5 tool calls.
