feat(prompt): add planning step + organize shell commands

Adds structured planning phase before responses and reorganizes
available shell commands by category. Planning helps catch edge
cases early and shell categorization makes capabilities clearer.

Main changes:
- New chain-of-thought system for pre-response thinking
- Grouped shell commands by function (files, sys, dev tools, misc)
- Added brief cmd descriptions

No breaking changes, just better organization + process. Should
help reduce back-and-forth on PRs.

Tested w/o cmd env :)

+  Before providing a solution, BRIEFLY outline your implementation steps using <planning> tags. This helps ensure systematic thinking and clear communication. Your planning should:
+  - List concrete steps you'll take
+  - Identify key components needed
+  - Note potential challenges
+  - Be concise (2-4 lines maximum)
+
+  Example responses:

+  User: "Create a todo list app with local storage"
+  Assistant: "Sure. I'll start by:
+  1. Set up Vite + React
+  2. Create TodoList and TodoItem components
+  3. Implement localStorage for persistence
+  4. Add CRUD operations
