Summary

Add AndroidTV/tvOS target support and enable tvOS runner-driven automation flows while reusing existing platform backends.

• Add --target mobile|tv selection through device/session selectors and docs.
• Add --platform apple alias that maps to the iOS/tvOS backend.
• Remove tvOS capability hard block so tvOS follows the iOS command matrix by device kind.
• Update iOS runner destination/build resolution to pick iOS vs tvOS based on selected target.
• Update runner XCTest behavior for tvOS navigation semantics:
  • back -> menu remote action fallback
  • home -> home remote action
  • app-switcher -> double-home remote action
  • directional swipe -> remote directional presses
• Make runner Xcode project multi-platform (iOS + tvOS) so tvOS destinations are valid.
• Keep AndroidTV launch/listing behavior category-aware (LEANBACK_LAUNCHER).
• Update README, website docs, and skills/agent-device with tvOS runner support details and the apple alias.

Validation

• pnpm typecheck
• pnpm test:unit
• pnpm test:smoke
• pnpm build:xcuitest
• pnpm test:integration (fails in current environment on existing Android settings snapshot label assertion mismatch)
• xcodebuild build-for-testing ... -destination "generic/platform=tvOS Simulator" (blocked in this environment: tvOS Simulator runtime not installed)
