fix: improve agentic tool descriptions for better model discovery

Tool descriptions now explicitly state when models should use them:
- Memory Store: 'Use when user asks to remember, recall, list memories'
- Task Manager: 'Use when user mentions tasks, todos, things to do'
- Structured Thinking: 'Use for complex questions requiring analysis'
- Decision Matrix: 'Use when comparing options or recommendations'
- Project Planner: 'Use for planning, roadmaps, breaking work into phases'

This helps smaller models understand WHEN to call these tools instead of
just responding with text claiming they don't have memory/capabilities.
