Mac Helper 1.6.7

Codex model and reasoning-effort selections now work reliably from Maccess AI.

What changed

• Fixes Codex tasks failing with “Invalid params” after selecting a model and reasoning effort.
• Keeps ACP model identifiers and reasoning-effort variants separate, including selections saved by earlier releases.
• No iPhone update is required; compatible with Maccess 1.6.0 and newer.
