🐍 Support for Python 3.13

We now support the latest version of Python, and have also upgraded various dependencies to ensure they all also support Python 3.13.

✅ Simplification of REST API schemas

We simplified the REST API for agent creation to pass in defaults for tools and agent type. Below is an example of agent creation via the REST API (documentation):

curl --request POST \
  --url http://localhost:8283/v1/agents/ \
  --header 'Content-Type: application/json' \
  --data '{
  "memory_blocks": [
    {
      "value": "The human'\''s name is Bob the Builder",
      "label": "human"
    },
    {
      "label": "persona",
      "value": "My name is Sam, the all-knowing sentient AI."
    }
  ],
  "llm_config": {
    "model": "gpt-4o-mini",
    "model_endpoint_type": "openai",
    "model_endpoint": "https://api.openai.com/v1",
    "context_window": 16000
  },
  "embedding_config": {
    "embedding_endpoint_type": "openai",
    "embedding_endpoint": "https://api.openai.com/v1",
    "embedding_model": "text-embedding-3-small",
    "embedding_dim": 8191
  }
}'
