feat(prompts): enhance plan output with TL;DR, agent profiles, and parallelization

- prometheus-prompt: Add TL;DR section with quick summary, deliverables, effort estimate
- prometheus-prompt: Add recommended agent profile (category + skills) per task
- prometheus-prompt: Enhance parallelization with execution waves and dependency matrix
- ultrawork: Change plan agent to prometheus agent invocation
- ultrawork: Add session_id resume workflow for Prometheus iteration
