Add Bouncer - Gemini quality gate for Claude Code

[federicodeponte]

Summary

Adding Bouncer to the Tools & Utilities section.

Bouncer is an independent quality gate that uses Gemini to audit Claude Code's output. It includes:

• Stop hook for automatic auditing of every Claude Code response
• Quick audit skill for on-demand checks
• Deep audit with full tool access for thorough verification
• One-liner install via curl

It solves the problem of having an independent model verify output quality, rather than trusting the same model that produced the work.
