This is just an experimental PR

To run this:

1. Build core, joi and extensions as usual
2. Run yarn dev:web:standalone
3. Voila - Access localhost:3000 on safari or chrome browser (there is a known issue with Arc, WIP)

Changes made

This pull request includes several changes to enhance the functionality and compatibility of the JanHQ application, particularly focusing on handling web and electron environments, improving theme management, and updating extension handling. The most important changes include modifications to the ExtensionManager class, the addition of a new theme, and updates to the build and development scripts.

Enhancements to Extension Handling:

• web/extension/ExtensionManager.ts: Added logic to handle extensions differently based on the environment (electron or web). This includes using WebExtensions for web environments and modifying the activateExtension method to simplify the URL handling for extensions. [1] [2] [3] [4]
• web/extensions.json: Added a JSON file that lists all available extensions with their metadata, which will be used in web environments.

Theme Management Improvements:

• web/hooks/useLoadTheme.ts: Added logic to load a default theme (DefaultTheme) when the application is running in a web environment. [1] [2]
• web/theme.json: Introduced a new theme configuration file to define the "Joi Light" theme, including various UI element styles.

Build and Development Script Updates:

• package.json: Added a new script dev:web:standalone for running the web application in standalone mode and updated the build:web script to fix a syntax issue.

Code Simplification:

• web/hooks/useModels.ts: Simplified the retrieval of models by replacing .toArray() with Array.from() for better readability and consistency. [1] [2] [3]

Compatibility Enhancements:

• extensions/inference-cortex-extension/src/index.ts: Added a check to ensure compatibility with environments that do not have electronAPI.
• web/hooks/useSendChatMessage.ts: Added logic to handle message requests differently based on the environment (electron or web). [1] [2]
