fix(wds): Move repository structure decision to naming stage (Step 2.2)

Critical UX improvement: Decision happens at the RIGHT moment.

Changes to Step 2.2 (Repository Settings):
- ADDED: Comprehensive 'Single vs Separate Repo' decision framework
- Decision now happens DURING naming (not after)
- Clear naming convention: 'my-project' vs 'my-project-specs'

Single Repository Use Cases:
✅ Close to development team
✅ Simple, direct communication needed
✅ Building the project yourself
✅ Working closely with other designers
✅ Small team with full ownership
✅ Rapid iteration and feedback

Separate Repository Use Cases:
✅ 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

Changes to Step 2.3:
- Acknowledge decision was made
- Remind about implications

Changes to Step 4.1:
- SIMPLIFIED: Just recap the decision made in Step 2
- No longer presenting options (already decided!)
- Cleaner flow

Reasoning:
Repository NAME determines structure. The decision must happen when
naming the repository, not later. This is when GitHub asks 'what do
you want to call this?' - that's the natural decision point.

Benefits:
- Decision at natural moment (when naming)
- Clear naming conventions prevent confusion
- Users understand implications before creating
- No 'oops, I named it wrong' moments
- Professional guidance on when to use each approach

 ### 2.2 Repository Settings
 
+**IMPORTANT: Your naming choice determines your structure!**
+
+### Single Repo or Separate Specs Repo?
+
+**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
+```
+
+**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
+
+**For this tutorial:**
+- Beginners: Use **Option A** (single repo like `dog-walker-app`)
+- Corporate/Enterprise: Use **Option B** (separate like `dog-walker-app-specs`)
+
+**Choose your name now based on your situation!**
+
+---
+
 **Repository Name:**
 - Use lowercase with hyphens
 - Descriptive and specific
-- Examples: `dog-walker-app`, `recipe-sharing-platform`, `fitness-tracker-specs`
+- Examples: `dog-walker-app` OR `dog-walker-app-specs`
 
 **Description:**
 - Short one-liner about your project
