This PR adds the second part of integrating Qwen with Claude Code Router as per Chapter 5. Includes:

  • Updated router logic
  • Fixed missing config references
  • Minor cleanups and improved structuring

Additional Note:
During our internal testing (special thanks to Daniyal Hashmi’s research), we observed that Claude’s configuration handling with Qwen produces more consistent and generous responses compared to Gemini. This update reflects those findings to improve developer experience.

Ready for review.

This commit completes the NotebookLM slides integration for Parts 1-3 and Part 5 (15 chapters total), and improves the pedagogical flow by repositioning slides before learning objectives.

## NotebookLM Slide Generation (11 new slides)
- Generated slides for Chapters 5-12 (Part 2 & Part 3)
- Generated slides for Chapters 31-33 (Part 5)
- All slides follow proficiency-calibrated prompt templates (A2/B1/C1)
- Total: 15/33 chapters now have slides (Parts 1-3 + Part 5)

## Pedagogical Improvement: "Before You Begin" Pattern
Changed slide placement across all 15 completed chapters:

**Before**:
```
## What You'll Learn
[objectives...]
## 📊 Chapter Slides
<PDFViewer.../>
```

**After**:
```
## 🎯 Before You Begin
<PDFViewer.../>
---
## What You'll Learn
[objectives...]
```

**Rationale**:
- Progressive disclosure: Big picture (slides) → Objectives → Content
- Action-oriented heading signals prerequisite, not optional
- Engages visual learners immediately
- Follows constitutional principle of "Right Altitude" pedagogical design

## Skill Documentation Improvements
Enhanced `.claude/skills/notebooklm-slides/SKILL.md` based on 15-chapter implementation:

## Issues Corrected

**ai-native-ide-landscape.png**:
- ❌ Previously showed: Cursor, Windsurf, Cline (incorrect IDEs)
- ✅ Now shows: Zed, Cursor, Antigravity (correct 3 AI-native IDEs from chapter)

**comparative-capstone.png**:
- ❌ Previously claimed: Antigravity supports BYOK (Bring Your Own Key) - FALSE
- ✅ Now states: Antigravity uses quota-based system tied to Google account - TRUE
- Changed persona: "Power User/Hacker" → "Experimental/Early Adopter" (more accurate)
- Updated description: Reflects actual free IDE with quota limits, not custom API keys

## Factual Corrections

**Antigravity (Google IDX)**:
- Reality: Free, cloud-native IDE with quota system
- Reality: Private beta, invitation-only access
- Reality: NO support for custom API keys (BYOK)
- Users hit quota limits quickly (reported in developer communities)

**Chapter Focus**:
- Book covers 3 AI-native IDEs: Zed, Cursor, Antigravity
- VS Code mentioned only as comparison point for Cursor (not a main focus)
- Comparison lesson builds same CLI app in all 3 IDEs

## Image Details

Both images now show factually accurate information:
- Zed: Performance-first, Rust-powered, open source, free
- Cursor: VS Code evolution, $20/month Pro, AI chat + autocomplete
- Antigravity: Agent control plane, Google workspace, quota-based (NOT BYOK)

…en-slides

Add NotebookLM slides integration for Chapters 13-23
Implemented composable, metadata-driven content enhancement system that
decouples slides integration from manual JSX, enabling cleaner content
and cloud-ready architecture.

## Architecture Changes

**New Plugin System** (`plugins/remark-content-enhancements/`):
- Main orchestrator with synchronous remark plugin pattern
- Composable transformer architecture for slides (extensible to quizzes, exercises)
- Build-time AST transformation using unist-util-visit
- Fixed frontmatter access: file.data.frontMatter (capital M) per Docusaurus spec

**Components**:
- `index.js`: Plugin entry point, reads frontmatter, coordinates transformers
- `transformers/slides.js`: Injects PDFViewer before "What You'll Learn" heading
- `package.json`: Plugin metadata and dependencies
- `README.md`: Architecture documentation and examples

**Integration**:
- Registered PDFViewer in `src/theme/MDXComponents.tsx`
- Added plugin to `docusaurus.config.ts` remarkPlugins array
- Supports both local paths and cloud URLs transparently

## Content Migration (33 Chapters)

Migrated all chapters from manual JSX to frontmatter metadata:

**Before** (deprecated):
```markdown
import PDFViewer from '@site/src/components/PDFViewer';
<PDFViewer src="slides/chapter-01.pdf" height={700} />
```

**After** (current):
```yaml
---
slides:
  source: "slides/chapter-01-slides.pdf"
  title: "Chapter 1: The AI Development Revolution"
  height: 700
---
```

**Chapters Updated**:
- Part 1 (Chapters 1-4): AI Development Revolution, AI Turning Point, Billion Dollar AI, Nine Pillars
- Part 2 (Chapters 5-9): Claude Code, Gemini CLI, Bash, AI IDEs, Git/GitHub
- Part 3 (Chapters 10-12): Markdown, Prompt Engineering, Context Engineering
- Part 4 (Chapters 13-30): Python Fundamentals (18 chapters)
- Part 5 (Chapters 31-33): Spec-Driven Development

## Benefits

1. **Cleaner Content**: Removed JSX imports and manual components from 33 README files
2. **Consistent Placement**: Automatic injection before "What You'll Learn" (no manual positioning)
3. **Cloud-Ready**: Architecture supports both `slides/file.pdf` and `https://cdn.example.com/file.pdf`
4. **Easier Maintenance**: Update YAML metadata instead of JSX code
5. **Composable Pattern**: Can extend to other enhancements (quizzes, interactive exercises)

## Documentation Updates

Updated `.claude/skills/notebooklm-slides/SKILL.md`:
- New "Metadata-Driven Architecture" section explaining the change
- Updated Step 6 integration instructions with frontmatter examples
- Added verification steps with build command
- Updated batch processing and automation workflows
- Documented cloud migration path

## Build Verification

✅ All 33 chapters build successfully
✅ Console logs confirm injection: `[Slides Transformer] ✅ Injected slides/chapter-XX-slides.pdf`
✅ HTML output verified: PDFViewer components render before "What You'll Learn"
✅ No broken links or build errors

## Technical Details

**Plugin Pattern**: Synchronous remark transformer (matches existing Python plugin)
**AST Manipulation**: Finds h2 "What You'll Learn" heading, injects component node before it
**Frontmatter Access**: Uses Docusaurus-specific `file.data.frontMatter` (capital M)
**Path Normalization**: Local paths → `/slides/file.pdf`, URLs → unchanged
**Component Registration**: PDFViewer globally available via MDXComponents

Following MCP SDK best practices:

Database Lifecycle (app.py):
- Add app_lifespan context manager with AppContext dataclass
- Initialize database on startup via init_db()
- Dispose database engine on shutdown via reset_engine()
- Pass lifespan to FastMCP constructor

Session Manager Lifecycle (server.py):
- Add starlette_lifespan for MCP session manager
- Wrap streamable_http_app in Starlette with lifespan
- Ensures proper session cleanup on server shutdown

This fixes potential connection leaks when the server shuts down,
as the database engine was never being disposed.

Problem:
- Previous design used singleton engine with connection pool
- Connections stayed open for server lifetime
- Not suitable for serverless (Cloud Run) or cloud DBs (Neon, Supabase)

Solution:
- Use NullPool - no local connection pooling
- Each request creates fresh connection, disposed immediately after
- Cloud database providers (Neon PgBouncer, Supabase) handle pooling
- Removed unnecessary lifespan management from app.py

Pattern for cloud databases:
```python
engine = create_async_engine(url, poolclass=NullPool)
async with session:
    # ... use session
# Connection released back to cloud pooler
await engine.dispose()
```

Benefits:
- Works with serverless (no warm connections needed)
- Compatible with Neon, Supabase, PlanetScale connection poolers
- No connection leaks on server restart
- Simpler lifecycle - no startup/shutdown hooks needed

Test fixtures updated to use StaticPool for in-memory SQLite.
