Subject: [PATCH] Add configuration system for RoslynBridge extension
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add appsettings.json with configurable settings:
  - WebApiUrl: URL of the WebAPI middleware (default: http://localhost:5001)
  - DefaultPort: Starting port for VS instances (default: 59123)
  - MaxPortRange: Number of ports to try (default: 10)
  - HeartbeatIntervalSeconds: Heartbeat interval (default: 60)

- Create ConfigurationService singleton to load settings
  - Loads from appsettings.json in extension directory
  - Falls back to sensible defaults if file missing
  - Provides easy property access

- Update RoslynBridge.csproj to include:
  - ConfigurationService.cs in compilation
  - appsettings.json as content (copied to output and included in VSIX)
  - System.Data reference for future use

This allows users to customize extension behavior without recompiling.
