* fix: make LiteLLM SDK embeddings encoding_format configurable (#925)
The hardcoded encoding_format='float' breaks providers like Voyage AI
(only accepts 'base64') and Gemini (doesn't support the parameter at all).
Add HINDSIGHT_API_EMBEDDINGS_LITELLM_SDK_ENCODING_FORMAT config option
that defaults to 'float' for backwards compatibility. Set to empty string
to omit the parameter for incompatible providers.
* chore: regenerate docs skill after configuration change
