Λήψη GitButler 0.15.2

## Experimental: Agentic Coding integration
If you are using tools like Cursor or Claude Code you can now better integrate GitButler in your workflow. Cursor/VSCode/Zed can now interact with GitButler over MCP, while Claude Code can be integrated via Hooks. You can read more on the docs page: https://docs.gitbutler.com/features/ai-integration/ai-overview

Both features are enabled via the "Experimental" feature toggle as we are tuning the behavior.

Please feel welcome to share any feedback, suggestions and requests on Discord, GitHub Issues or the in-app feedback button so that we can create the best workflow possible.
