feat: add research agent phase to Ralph wizard

Adds a new Phase 0 research agent that runs before all other analysis agents:
- Web search for GitHub repos, documentation, tutorials
- Codebase exploration for existing patterns
- Technical recommendations and potential challenges
- Creates enriched task description for downstream agents
- Research context injected into all analysis agents via {RESEARCH_CONTEXT}
- Saves output to research/ folder with prompt.md and result.json
