Consolidate sabbath-school-reproducer into monorepo structure

[Surgbc]

Problem

Currently, the Sabbath School lessons processing workflow is split across multiple repositories:

1. This repository (lessons): Contains lesson content, OCR processing scripts, and monorepo structure setup
2. sabbath-school-reproducer: Contains the PDF generation functionality

This separation creates several issues:

• Fragmented workflow: Users need to manage multiple repositories for a single process
• Missing functionality: The package.json references apps/* and packages/* workspaces that don't exist
• Complex dependencies: The reproducer must be installed separately as a PyPI package
• Inconsistent tooling: Different repositories use different development workflows

Current State

The monorepo structure was partially implemented in commit 096988d with:

• ✅ Turbo monorepo configuration in package.json
• ✅ PDF processing scripts for downloading and OCR
• ✅ Lesson content organization and management
• ❌ Missing apps/ and packages/ directories
• ❌ Missing PDF generation capability (exists in separate repo)

Proposed Solution

Integrate the sabbath-school-reproducer functionality into this monorepo as a workspace package:

Structure

lessons/
├── apps/
│   └── lesson-processor/          # Main CLI application
├── packages/
│   ├── pdf-generator/            # Core PDF generation (from reproducer)
│   ├── lesson-parser/            # Lesson content parsing
│   └── shared-config/            # Shared configuration types
├── scripts/                      # Existing OCR and download scripts
├── data/                         # Existing lesson data
└── lessons/                      # Existing lesson content

Benefits

• Unified workflow: Single repository for complete lesson processing pipeline
• Simplified development: Unified tooling with Turbo monorepo
• Better integration: Direct imports between packages
• Consistent versioning: Single source of truth for releases
• Improved CI/CD: Unified testing and deployment pipeline

Implementation Plan

1. Create workspace structure: Add missing apps/ and packages/ directories
2. Migrate reproducer code: Move sabbath-school-reproducer into packages/pdf-generator/
3. Update dependencies: Integrate WeasyPrint and other PDF dependencies
4. Unify configuration: Ensure config.yaml format compatibility
5. Update scripts: Modify existing scripts to use local packages
6. Documentation: Update README with unified workflow instructions

Expected Outcome

A complete lesson processing monorepo where users can:

1. Download historical lesson PDFs
2. Process them through OCR to markdown
3. Generate new PDFs from markdown content
4. Deploy lesson indexes to GitHub Pages

All within a single, well-organized repository structure.
