Create Memory Capture API

This ticket involves creating a Node.js-based internal API or script that the AI agent can use to save a "memory" into the ChromaDB instance set up in the previous ticket. This is the mechanism by which the agent's state will be persisted.

Acceptance Criteria

1. A new script is created (e.g., buildScripts/ai/addMemory.mjs).
2. The script accepts the following inputs:
   • User Prompt (text)
   • Agent Response (text, including tool calls)
   • Agent Thought Process (text)
3. The script generates a semantic embedding for the combined text content.
4. The script saves the content and its embedding as a new document in the neo-agent-memory ChromaDB collection, along with metadata (e.g., timestamp, session ID).
