chore(benchmarks): remove POC benchmark

[mabry1985]

Summary

• Remove benchmarks/roguelike-ai-poc/ (POC idea + reference artifacts).
• Replace the example used in the first-plan tutorial and the data-model reference with a neutral contact-list-deduper example.
• benchmarks/ directory stays as a convention; new benchmarks can be added per the layout in benchmarks/README.md.

Test plan

• grep -rn roguelike returns nothing in the repo.
• CI passes (unaffected; docs-only + benchmark-dir change).

🤖 Generated with Claude Code

Summary by CodeRabbit

• Documentation

  • Updated benchmark documentation to clarify expected directory structure and guidance.
  • Updated tutorial examples to feature a contact list deduplication CLI instead of previous examples.
  • Updated ID convention examples in reference documentation.

• Chores

  • Removed legacy benchmark reference materials and associated documentation.

Walkthrough

This PR removes the roguelike-ai-poc benchmark and updates benchmark infrastructure documentation, then refactors tutorials and examples to demonstrate the tool using a new contact-list deduplication CLI scenario instead of the prior roguelike benchmark.

Changes

Benchmark cleanup and documentation refactor

Layer / File(s)	Summary
Benchmark structure documentation benchmarks/README.md, benchmarks/roguelike-ai-poc/reference/tasks/T0003-implement-frame-renderer.md	Benchmark README documents the expected directory structure (benchmarks/<name>/prompt.md, reference/, run.sh) and clarifies that no public benchmarks are yet committed. The roguelike benchmark directory and its task/decision metadata are removed.
Tutorial and reference documentation updates docs/README.md, docs/reference/data-model.md, docs/tutorials/your-first-plan.md	Tutorial is refactored to use a contact-list deduplication CLI example (fuzzy matching, CSV handling) instead of the roguelike benchmark. Sample wizard output, CLI arguments, and ID convention examples are updated. Lens review text clarifies that skeptic reviews appear only under mvp/full presets, not poc.
