RFC: Add Skill Types Taxonomy to LevelUp Extension

[kanfil]

Summary

Add Anthropic's 9-category Skill Types Taxonomy to the LevelUp extension to guide CDR classification during discovery.

Motivation

When discovering CDRs, teams need guidance on what type of skill to build. Anthropic's Claude Code team documented a 9-category taxonomy that helps answer "What type of skill should this be?"

Reference: Lessons from Building Claude Code: How We Use Skills

• Infrastructure Operations

2. Update Extension Defaults (extension.yml)
