Add missing rotary-embedding-torch dependency for macOS builds

[Copilot]

PyInstaller's CDMF.spec references rotary_embedding_torch as a hidden import but the package was not installed, causing macOS build failures.

Changes

• Added rotary-embedding-torch==0.8.9 to requirements_ace_macos.txt
• Added rotary-embedding-torch==0.8.9 to requirements_ace.txt for consistency

The package is a transitive dependency of ACE-Step and required for proper PyInstaller bundling.

Original prompt

The failure in the macOS build contains several issues preventing completion. The resolution steps are outlined below:\n\n1. Missing Dependency:\n - The log indicates that rotary_embedding_torch is not installed, triggering PyInstall to raise:\n ```\n ERROR: Hidden import `rotary_embedding_torch\n ]
