ProxyBridge for macOS v4.0.0

⚠️ Breaking Changes

v4.0.0 is a major release and is not backwards compatible with any previous version of ProxyBridge.

• All locally stored data from older versions—including proxy configurations, proxy rules, profiles, and app settings—will not carry over and must be reconfigured from scratch.
• There is no automatic migration. Please note down your existing rules and configuration before upgrading.
