Sækja BrightScript Emulator 2.6.2

This release bumps `brs-engine` to v2.6.1 and `brs-scenegraph` to v0.6.1, completing the two **Roku OS 16.0** features left out of the previous engine release. `roUrlTransfer` now supports **Server-Sent Events (SSE)** through the new `AsyncGetSSEvents()` method, delivering streaming `roSSEvent`s to the message port, and the SceneGraph `ChannelStore` node gains the **`GetRokuCustomerId`** command, sent through its generic request framework (`request`/`requestStatus` fields) and returning the new `customerId` device-information property, now configurable in the **Device** settings. The documented Roku OS baseline is now 16.0. On the simulator side, the packaged app shrinks from 193 MB to 45 MB, a batch of SonarCloud reliability findings is cleared (with the Sonar rules now also enforced by the local lint), and `electron-builder` is upgraded to 26.15.3.

See the **BrightScript Simulation Engine** v2.6.1 [full changelog](https://github.com/lvcabral/brs-engine/releases/tag/v2.6.1) for all the language and framework features and improvements.
