Optimization SDK Sync

Update the modern Optimization SDK knowledge in contentful-personalization from a verified upstream revision. Optimize the result for an agent solving implementation tasks: concise, explicit, runtime-specific, and grounded in public API and maintained examples.

Do not copy upstream guides wholesale. Treat this as a knowledge compilation workflow.

Scope

This skill owns modern @contentful/optimization* guidance. Preserve legacy @ninetailed/* guidance unless upstream evidence requires a compatibility correction.

Supported runtime references:

• shared concepts and behavior
