[perf] Fix Float32Array test assertions and link adapter

Fix the remaining Float32Array usage that was causing test failures:
- Update test assertions to expect regular arrays instead of Float32Array
- Convert link adapter Float32Array creation to regular arrays

Resolves: AssertionError: expected [ 50, 60 ] to deeply equal Float32Array[ 50, 60 ]
