Detailed Description

Result of ContextBuilder::release(): the raw native builder handle paired with the heap-owned progress callback (if any).

The caller takes joint ownership. If callback_owner is non-null, the native side stores a raw pointer into it and will invoke the callback until the native context built from builder is freed. Therefore callback_owner must remain alive at least until the native context returned by c2pa_context_builder_build(builder) is freed via c2pa_free(). Release order: native context first, then callback_owner goes out of scope.
