refactor(wds): Combine GitHub account and repository into single lesson

Streamlined Module 02 from 6 lessons to 5:

Changes:
- COMBINED: lesson-01-github-account + lesson-02-create-repository
- NEW: lesson-01-setting-up-github (both account AND repository)
- RENAMED: All subsequent lessons renumbered (02-05)
- UPDATED: All navigation links between lessons
- UPDATED: Module overview with 5-lesson structure

New Lesson Structure:
01. Setting Up GitHub (15-20 min) - Account + Repository
02. Install IDE (10 min)
03. Git Setup (5 min)
04. Clone & Add WDS (15-20 min)
05. Initiate Mimir (5 min)

Benefits:
- More logical flow (GitHub setup together)
- One less context switch
- Still focused and digestible
- Cleaner progression
- Total time unchanged (45-60 min)

Old separate lessons removed.

+# Lesson 01: Setting Up GitHub
+
+**Create your GitHub account and project repository**
+
+---
+
+## What You'll Do
+
+- Create GitHub account
+- Choose professional username
+- Create or join a project repository
+- Decide on repository structure (single vs separate)
+
+**Time:** 15-20 minutes
+
+---
+
+## Part 1: Create Your GitHub Account
+
+### What is GitHub?
+
+Think of GitHub as:
+- **Professional cloud storage** for your project files
+- **Time machine** - every change saved, can go back to any version
+- **Collaboration tool** - work with others seamlessly
+
+**For designers:** GitHub is where your WDS specifications will live, backed up and version-controlled.
+
+---
+
+### Step 1: Sign Up
+
+1. Go to **https://github.com**
+2. Click the green **"Sign up"** button (top right)
+3. Enter your email address
+4. Create a password (make it strong!)
+5. Choose a username
+
+**Username Tips:**
+
+✅ **Professional** - You might share this with clients  
+✅ **Simple** - Easy to remember and spell  
+✅ **Memorable** - Represents you or your work
+
+**Good Examples:**
+- `john-designer`
+- `sarahux`
+- `mike-creates`
+- `[yourname]-design`
+
+6. Verify you're human (solve the puzzle)
+7. Check your email and click the verification link
+
+**✅ Checkpoint:** You can log in to GitHub!
+
+---
+
+## Part 2: Create Your Project Repository
+
+### What is a Repository?
+
+A **repository** is a folder that GitHub tracks. Every change you make is saved, and you can always go back to any version.
+
+---
+
+### Step 2: Choose Your Scenario
+
+**Which situation applies to you?**
+
+**Scenario A: Starting a New Project** (Continue to Step 3 below)
+- You're starting fresh
+- No existing repository
+- You control the setup
+
+**Scenario B: Joining an Existing Project** (Skip to Step 7 below)
+- Team project already exists
+- Client has existing repository
+- Contributing to ongoing work
+
+**Scenario C: Just Learning WDS** (Skip this lesson)
+- You're just learning WDS methodology
+- Not starting a project yet
+- **→ [Continue to Lesson 02: Install IDE](../lesson-02-install-ide/tutorial.md)**
+
+**Most beginners: Use Scenario A**
+
+---
+
+## Scenario A: Create New Repository
+
+### Step 3: Navigate to Repositories
+
+1. After logging in, click your **profile icon** (top right)
+2. Click **"Your repositories"**
+3. Click the green **"New"** button
+
+---
+
+### Step 4: Choose Repository Structure
+
+**IMPORTANT: Your naming choice determines your structure!**
+
+#### Option A: Single Repository
+
+**Name it simply:**
+- `dog-walker-app`
+- `recipe-platform`
+- `fitness-tracker`
+
+**Structure:**
+```
+dog-walker-app/
+├── docs/              ← Your WDS specifications
+└── src/               ← Code
+```
+
+**Use when:**
+- ✅ You're close to the development team
+- ✅ You want simple, direct communication
+- ✅ You're building the whole project yourself
+- ✅ Working closely with other designers
+- ✅ Small team with full ownership
+- ✅ Rapid iteration and feedback
+
+---
+
+#### Option B: Separate Specifications Repository
+
+**Name with `-specs` suffix:**
+- `dog-walker-app-specs`
+- `recipe-platform-specs`
+- `fitness-tracker-specs`
+
+**Structure:**
+```
+dog-walker-app-specs/     ← This repo (specifications only)
+dog-walker-app/           ← Separate code repo (create later)
+```
+
+**Use when:**
+- ✅ Corporate or enterprise environment
+- ✅ Specifications serve multiple products/platforms
+- ✅ Development team has many developers
+- ✅ Extensive or complex codebase
+- ✅ Clear handoff boundaries needed
+- ✅ Design and dev have separate workflows
+
+---
+
+### Step 5: Repository Settings
+
+**Repository Name:**
+- Use lowercase with hyphens
+- Descriptive and specific
+- Examples: `dog-walker-app` OR `dog-walker-app-specs`
+
+**Description:**
+- Short one-liner about your project
+- Example: "UX specifications for Dog Week family coordination app"
+
+**Public vs Private:**
+- **Public:** Anyone can see (good for portfolio projects)
+- **Private:** Only you and invited collaborators (good for client work)
+
+**Initialize with README:**
+- ☑️ **Check this box!** It creates a starter file
+
+**DO NOT** add .gitignore or license yet (we'll do this later)
+
+---
+
+### Step 6: Create Repository
+
+Click the green **"Create repository"** button
+
+**✅ Checkpoint:** You see your new repository with a README file
+
+**Remember your choice:**
+- Single repo (`my-project`)? Specs and code together
+- Separate repo (`my-project-specs`)? You'll create a second repo for code later
+
+**[Continue to Lesson 02: Install IDE →](../lesson-02-install-ide/tutorial.md)**
+
+---
+
+## Scenario B: Joining Existing Repository
+
+### Step 7: Request Repository Access
+
+**Email template for repository owner or team lead:**
+
+```
+Hi [Name],
+
+I'd like to contribute to [project-name] using WDS methodology. 
+Could you add me as a collaborator to the repository?
+
+My GitHub username: [your-username]
+
+Thank you!
+```
+
+**They will:**
+1. Go to repository settings
+2. Click "Collaborators"
+3. Add your GitHub username
+4. You'll receive an email invitation
+
+---
+
+### Step 8: Accept the Invitation
+
+1. Check your email for GitHub invitation
+2. Click **"Accept invitation"**
+3. Or go to the repository URL directly
+4. You'll see an invitation banner → Click **"Accept"**
+
+---
+
+### Step 9: Understand the Existing Structure
+
+**Before cloning, check what structure they're using:**
+
+**Look at the repository name:**
+- `project-name` → Likely single repo (specs + code together)
+- `project-name-specs` → Separate specs repo (code elsewhere)
+
+**Browse the repository:**
+- Has `docs/` folder? → Probably already using WDS!
+- Has `src/` or `app/` folder? → Code lives here too (single repo)
+- Only documentation? → Separate specs repo
+
+**When in doubt:** Ask the team lead!
+
+**✅ Checkpoint:** Invitation accepted, you understand the structure
+

+
+---
+
+## Troubleshooting
+
+**Issue:** Didn't receive verification email  
+**Solution:** Check spam folder, or click "Resend verification email"
+
+**Issue:** Username already taken  
+**Solution:** Try variations with hyphens or numbers (`john-ux-2`, `sarah-designs`)
+
+**Issue:** Repository name already taken  
+**Solution:** Add your username: `yourname-project-name`
+
+**Issue:** Don't know which structure to use  
+**Solution:** Ask your team lead, or use single repo (simpler for beginners)
+
+**Issue:** Invitation expired  
+**Solution:** Ask repository owner to resend invitation
