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.

+## Progress Tracking
+
+Track the 3-phase review process with task dependencies:
+
+```
+Task 1: Collect - blocked by nothing
+Task 2: Reflect - blocked by Task 1
+Task 3: Plan - blocked by Task 2
+
+[Spinner] Phase 1: Collecting from daily notes...
+[Done] Phase 1 complete
+[Spinner] Phase 2: Reflecting on goals...
+[Done] Phase 2 complete
+[Spinner] Phase 3: Planning next week...
+[Done] Weekly review complete (3/3 phases)
+```
+
+Dependencies ensure phases complete in order. Task tools provide visibility into the 30-minute review process.
