Subject: [PATCH] test: remove obsolete TensorFlow.js patch tests

Remove tensorflow-patch.test.ts which tested functionality that no longer exists after the migration to Transformers.js in v0.46. These tests were failing because they expected TensorFlow.js-specific global patches that are not present in the new Transformers.js implementation.
