"""
Sprint 47 tests: skill-backed slash commands appear in the Web UI autocomplete.

Covers:
- commands.js lazily loads /api/skills for slash autocomplete
- built-in commands still win over skill name collisions
- boot.js primes the async skill load when typing '/'
- the dropdown marks skill-backed entries visually
