* fix: address review feedback on frontmatter and consistency

- Switch description from folded block scalar (>) to single-quoted string
  per AGENTS.md documented format
- Fix Module 7 heading: backtick-wrap @ separately from 'file mentions'
  to avoid implying '@ file mentions' is a literal command
- Fix Final Exam Q6: change '@ + filename' to '@filename' with example
  to match the @src/auth.ts syntax taught in modules
- Fix Final Exam Q7: add GEMINI.md to match Module 7 precedence list

* fix: rename curriculum/ to references/ per agentskills.io spec

Addresses review feedback from @aaronpowell on PR #915.
The Agent Skills specification defines references/ as the standard
directory for supplementary documentation that agents read on demand.

- Renamed skills/cli-mastery/curriculum/ → references/
- Updated all path references in SKILL.md
- Updated asset paths in docs/README.skills.md

Module 5: Skills System

What are skills?

Specialized capability packages the AI can invoke
Think of them as "expert modes" with domain-specific knowledge
Managed via /skills command

Skill locations

Level	Location
User	`~/.copilot/skills/<name>/SKILL.md`
Repo	`.github/skills/<name>/SKILL.md`
Org	Shared via org-level config

Creating a custom skill

Create the directory: mkdir -p ~/.copilot/skills/my-skill/
Create SKILL.md with YAML frontmatter (name, description, optional tools)
Write detailed instructions for the AI's behavior
Verify with /skills

Skill design best practices

Clear description — helps the AI match tasks to your skill automatically
Focused scope — each skill should do ONE thing well
Include instructions — specify exactly how the skill should operate
Test thoroughly — use /skills to verify, then invoke and check results

Auto-matching

When you describe a task, the AI checks if any skill matches and suggests using it.
