* ✨ feat: Add support for new GPT-5.4 and GPT-5.4-pro models

- Introduced new token values and cache settings for 'gpt-5.4' and 'gpt-5.4-pro' in the API model configurations.
- Updated maximum output limits for the new models in the tokens utility.
- Included 'gpt-5.4' and 'gpt-5.4-pro' in the shared OpenAI models list for consistent access across the application.

* 🔧 update: Enhance GPT-5.4 and GPT-5.4-pro model configurations

- Refined token pricing and cache settings for 'gpt-5.4' and 'gpt-5.4-pro' in the API model configurations.
- Added tests for cache multipliers and maximum token limits for the new models.
- Updated shared OpenAI models list to include 'gpt-5.4-thinking' and added a note for verifying pricing before release.

* 🔧 update: Add clarification to token pricing for 'gpt-5.4-pro'

- Added a comment to the 'gpt-5.4-pro' model configuration in tokens.ts to specify that it shares the same token window as 'gpt-5.4', enhancing clarity for future reference.
