Re-implements the workflow enhancements that were reverted in #437.
Changes:
- Add ultrawork-mode section with agent utilization principles, execution rules,
TDD workflow, and zero-tolerance failure guidelines
- Add analyze-mode section for context gathering before execution
- Add CRITICAL: First Steps section requiring full conversation reading and
immediate todo creation
- Includes PR inline review comments and review bodies in context gathering
This restores the functionality from #430 to ensure the agent:
- Reads full issue/PR context before taking action
- Creates todos immediately after reading context
- Follows structured parallel execution patterns
