## Changes
1. **Support ESC environment variable names**
- Fallback to R2_ADMIN_ACCESS_KEY_ID if R2_ACCESS_KEY not set
- Fallback to R2_ADMIN_SECRET_ACCESS_KEY if R2_SECRET_KEY not set
- Allows script to work with Pulumi ESC (beanflows/prod) variables
2. **Use landing bucket path**
- Changed R2 path from `psd/{etag}.zip` to `landing/psd/{etag}.zip`
- All extracted data goes to landing bucket for consistent organization
3. **Updated Pulumi ESC environment**
- Added R2_BUCKET=beanflows-data-prod
- Fixed R2_ENDPOINT to remove bucket path (now just account URL)
## Testing
- ✅ R2 upload works: Uploaded to landing/psd/316039e2612edc1_0.zip
- ✅ R2 deduplication works: Skips upload if file exists
- ✅ Local mode still works without credentials
