feat: Add Cloudflare R2 stdlib registry upload + bump to v1.0.0

[shivasurya]

🎯 Overview

This PR adds automated Python stdlib registry uploads to Cloudflare R2 and bumps the version to 1.0.0.

✨ What's New

📦 Version Bump

• Version: 0.0.34 → 1.0.0
• Updated sourcecode-parser/VERSION and package.json

☁️ Cloudflare R2 Integration

• New GitHub Action: .github/workflows/stdlib-r2-upload.yml
  • Runs on release publish
  • Supports manual workflow dispatch
• Upload script: sourcecode-parser/tools/upload_to_r2.sh
  • Generates stdlib for Python 3.11, 3.12, 3.14
  • Uploads to R2 using AWS S3 sync
  • Uses --delete flag to replace existing registries
• Testing script: sourcecode-parser/tools/test_generation_local.sh
  • Validates generation without uploading

🔗 URL Migration

Old: https://codepathfinder.dev/assets/registries/...
New: https://assets.codepathfinder.dev/registries/...

Updated files:

• sourcecode-parser/tools/generate_stdlib_registry.py (manifest base_url)
• sourcecode-parser/graph/callgraph/builder/builder.go (Go client)
• sourcecode-parser/graph/callgraph/registry/stdlib_remote.go (comments)

🧹 Cleanup

• Removed .github/workflows/deploy.yml (Cloudflare Pages - now using Netlify)

📚 Documentation

• Added R2_SETUP.md with complete setup instructions
• Documents required GitHub secrets and Cloudflare configuration

🧪 Testing

✅ Local testing completed:

• Generated 190 modules for Python 3.14
• Total size: 8.2MB (well within 10GB free tier)
• Validated JSON structure
• Confirmed manifest base_url is correct
• Failed Windows-only modules (expected on macOS): msvcrt, nt, winreg, winsound

🔑 Required Secrets (Already Added)

The following GitHub secrets are configured:

• ✅ R2_ACCOUNT_ID
• ✅ R2_ACCESS_KEY_ID
• ✅ R2_SECRET_ACCESS_KEY

📋 Cloudflare R2 Setup Checklist

See R2_SETUP.md for detailed instructions.

• R2 bucket code-pathfinder-assets created
• Custom domain assets.codepathfinder.dev configured (DNS CNAME)
• Public access enabled on bucket
• GitHub secrets configured
• Test workflow dispatch after merge

🚀 How It Works

1. On Release: When you publish a new release (e.g., v1.0.0):

   • GitHub Action triggers automatically
   • Generates stdlib for Python 3.11, 3.12, 3.14
   • Uploads to R2 (replaces existing files)
   • Verifies public URLs are accessible

2. Manual Trigger: Go to Actions → "Upload Stdlib Registries to R2" → Run workflow

3. Lazy Loading: Go client downloads modules on-demand from:

   • https://assets.codepathfinder.dev/registries/python3.11/stdlib/v1/manifest.json
   • https://assets.codepathfinder.dev/registries/python3.12/stdlib/v1/manifest.json
   • https://assets.codepathfinder.dev/registries/python3.14/stdlib/v1/manifest.json

💰 Cost

Storage: 25-30 MB / 10 GB free tier = $0/month
Operations: ~100/month / 1M free = $0/month
Egress: Unlimited free = $0/month

Total: $0/month ✅

⚠️ Breaking Changes

• Stdlib registry URL changed (backward compatibility intentionally removed)
• Go client already updated to use new URL

📝 Next Steps

After merging:

1. Complete R2 custom domain setup (if not done)
2. Test workflow dispatch to verify R2 upload works
3. Create v1.0.0 release to trigger automatic upload
4. Verify registries are publicly accessible
