Add tvOS platform support

[setoelkahfi]

What

tvOS simulators now surface through the MCP server, so an MCP client can find and control them the same way it does iOS simulators.

Changes

• Accepts tvos in the platform unions and validation in the mobilecli wrapper.
• Drops the hard ios filter on simulator discovery, so tvOS simulators are returned. Analytics now reports each device's real platform instead of a hardcoded ios.
• Lists the tvOS Siri Remote buttons (UP, DOWN, LEFT, RIGHT, SELECT, MENU, PLAY_PAUSE) in the press-button tool description.

Depends on

• feat: Add tvOS simulator support mobilecli#292: provides the tvos platform and the Siri Remote button mapping
• Add tvOS UITest runner support devicekit-ios#53: the tvOS UITest runner that mobilecli installs and drives

Testing

With a booted tvOS simulator, mobile_list_available_devices returns it and mobile_press_button moves its focus.

Walkthrough

The change adds "tvos" as a supported platform across the codebase. In src/mobilecli.ts, the MobilecliDevicesOptions.platform and MobilecliDevicesResponse device platform type unions are widened to include "tvos", and the getDevices runtime validation and error message are updated accordingly. In src/server.ts, MobilecliDevice.platform is similarly widened, simulator discovery queries now include tvOS alongside iOS, posthog telemetry for simulators uses device.platform instead of a hardcoded "ios" string, and the mobile_press_button tool's button list is expanded with tvOS-specific buttons.

Make button machine-validatable, not description-only.

button is still a free-form string, so clients cannot validate or autocomplete the new tvOS buttons from the schema, and typos will only fail deeper in the stack. If this is a closed set, prefer a shared z.enum(...) here.

In `@src/server.ts` at line 521, The `button` field in the schema is still defined
as a free-form `z.string()` in `server.ts`, so it cannot be machine-validated or
autocompleted. Replace it with a shared `z.enum(...)` covering the supported
button values, and reuse that enum in the relevant schema so the `button`
constraint is enforced at validation time rather than only described in text.
