feat(telemetry): add Otel4Vsix integration (#22)

- Add CodingWithCalvin.Otel4Vsix package reference
- Configure telemetry in BreakpointNotifierPackage with Honeycomb export
- Add HoneycombConfig.cs for API key placeholder
- Instrument debugger events with activities and logging
- Add proper telemetry shutdown in Dispose
- Remove explicit DeployExtension (VsixSdk handles this)
