Rig v0.15 - bug fixes & instantiate DynClientBuilder from values!

[joshua-mo-143]

Hi everyone! I'm happy to announce that Rig v0.15 is finally up and live.

Added

• You can now instantiate DynClientBuilder from arbitrary values using DynClientBuilder::from_val. Useful if you need to grab your API keys outside of environment variables at runtime!
• Added .extended_details() to PromptRequest - get extra details about your prompt.

Bug Fixes

• Ollama should now properly return multiple results for tools
• prompting OpenAI Responses API with message history should now correctly fix itself
• Gemini functions have been moved to Vec<T> rather than OneOrMany<T> in the case that you don't have any tools or functions you want to use

Happy building!
