Add format consistency checker example for another AI platform

[YuhaoLin2005]

What

The format-consistency/ directory documents config format drift patterns for Claude Code. Add equivalent documentation for another AI agent platform: Cursor Rules, GitHub Copilot instructions, Windsurf rules, or your platform of choice.

Should include

1. The platform's config file structure and format conventions
2. Common drift patterns (headings change, indentation shifts, bullet styles diverge)
3. How drift degrades AI behavior on that platform
4. Detection approach (mechanical diff/lint, not AI judgment)
5. Example of a drifted config vs clean config

Why this matters

Format consistency was independently validated by SwarmAI's T-CBB as an operational invariant (OP8). Different platforms have different format vulnerabilities — documenting them makes the insight portable.

Notes

• See format-consistency/ for the existing Claude Code analysis
• This is documentation contribution — no code required
• Pick the platform you use daily
