refactor: replace replan commands with direct agent-based fixes

Replace batch replan workflow with TodoWrite tracking and direct agent calls:
- concept-clarify.md: Call conceptual-planning-agent for concept gaps
- action-plan-verify.md: Call action-planning-agent for task/plan issues

Both commands now require explicit user confirmation before fixes.
