Is your feature request related to a problem? Please describe.
Create a config.json file in repo so we do a version of configcat/firebase remote config, but directly from the repo, and consume those configuration variables from there.

Describe the solution you'd like
There should be a config.json in the main repo path, and this should include all prompts from prompts.dart in a "template" way,

Based on the following recording transcript of a conversation, provide structure and clarity to the memory in JSON according rules stated below.
The conversation language is $languageCode. Make sure to use English for your response.

${forceProcess ? "" : "It is possible that the conversation is not worth storing, there are no interesting topics, facts, or information, in that case, output an empty title, overview, and action items."}
    
For the title, use the main topic of the conversation.
For the overview, use a brief overview of the conversation.
For the action items, include a list of commitments, scheduled events, specific tasks or actionable steps.
For the category, classify the conversation into one of the available categories.
        
Here is the transcript ```$transcript```.
    
The output should be formatted as a JSON instance that conforms to the JSON schema below.

This config should be retrieved on main.dart, and stored in preferences.

should be in the JSON file in a way we could do .replaceAll and set the proper variables, so we can change the repo, and users will receive the updates.

Describe alternatives you've considered
Config cat/firebase, but this is better.
