Fetch curriculum standards frameworks from the CASE Network 2 API and align items to learning objectives

Steps

1. Identify the CASE Network 2 host URL (managed by Common Good Learning Tools) and browse the /ims/case/v1p0/CFDocuments endpoint to list all published frameworks including state standards.
2. Retrieve a specific framework document with GET /ims/case/v1p0/CFDocuments/{identifier}; the response includes title, subject, grade levels, and language metadata.
3. Fetch the full framework tree with GET /ims/case/v1p0/CFPackages/{identifier} which returns the CFDocument plus all CFItems and CFAssociations in a single response.
4. Each CFItem has an identifier (UUID), humanCodingScheme (e.g., CCSS.Math.Content.3.OA.A.1), and fullStatement (the standard text); store these for matching.
5. To align a lesson or assessment item, perform a text similarity search against CFItem fullStatement values and record the winning CFItem identifier as the alignment association.
6. Write alignment metadata back to your content object referencing the CFItem identifier and the CASE framework document identifier so consumers can traverse the full standard hierarchy.
