Add trace-my-code to Agent Skills

[kgohil]

Adds trace-my-code to the 🧠 Agent Skills list.

• Repo: https://github.com/kgohil/trace-my-code (public, MIT, valid SKILL.md)
• Keeps a living trace of the codebase — domain language, architecture, reuse patterns — current via a drift hook, so a coding agent reads it and reuses what already exists instead of rebuilding it.
• One entry added in the section's - [**name**](url) - (⭐) - description format.
