Summary

• repoint selected BSL crate LICENSE symlinks to licenses/apache2.txt
• add the missing Unreal SDK LICENSE symlink to licenses/apache2.txt

Requested crates/SDK:

• bindings-macro
• bindings-sys
• bindings
• lib
• primitives
• query-builder
• sats
• unreal SDK

Note: query-builder was already pointing at licenses/apache2.txt, so it has no diff.

Testing

• Verified all requested LICENSE paths resolve to ../../licenses/apache2.txt
• cargo run -p check-license-symlinks does not complete cleanly in this checkout because it also scans unrelated existing copied template files and node_modules license files that are not symlinks
