Add session task tools for progress visibility

Integrate Claude Code's task tools (TaskCreate, TaskUpdate, TaskList)
into skills and agents to provide spinner updates during multi-step
operations like morning routines, weekly reviews, and batch processing.

- Add task tools to allowed-tools in daily, weekly, goal-tracking skills
- Add task tools to 4 agents (inbox-processor, weekly-reviewer, etc.)
- Create task-tracking.md rule with naming conventions and best practices
- Document progress patterns with concrete spinner output examples
- Update CLAUDE.md and README.md with progress visibility feature

Task tools are session-scoped progress indicators that complement (not
replace) the existing markdown checkbox system in daily notes.
