Adds a native Android TV application that runs the full LedGrab Python server in-process via Chaquopy. Captures the TV box screen using the MediaProjection API and exposes the existing web UI on the device's local network — users configure via phone/tablet browser. Android (new /android/ module): - Kotlin shell: MainActivity, CaptureService (foreground service), ScreenCapture (MediaProjection + ImageReader), PythonBridge (Chaquopy). - Polished Leanback-themed UI with QR code for easy web UI access. - AGP 8.9 + Chaquopy 17 + Gradle 8.11 (avoids the AGP 8.7 thread-lock bug). - Pre-built pydantic-core wheels for arm64-v8a, x86_64, x86 cross-compiled with maturin + Android NDK, linked against Chaquopy's libpython3.11.so. Python server platform guards: - New utils/platform.py with is_android()/is_windows()/is_linux() helpers. - Guard every top-level import of desktop-only packages (mss, psutil, sounddevice, pyserial, PyAudioWPatch, etc.) with try/except ImportError. - Android-incompatible calls gated with None-checks so the server runs on reduced capabilities on Android (no CPU/RAM metrics, no mss displays). - utils/image_codec.py gains a Pillow fallback for resize + JPEG encode when cv2 is unavailable; all internal cv2.resize callers migrated. - New android_entry.py start_server/stop_server invoked from Kotlin. - get_displays API falls back to best available engine when mss fails. New capture engines: - MediaProjectionEngine: receives RGBA frames pushed from Kotlin through a thread-safe queue; caches last frame for static-screen previews. - ScrcpyClientEngine: optional H.264 streaming via scrcpy-client library (priority 10, overrides the ADB-screencap engine when installed). Frontend: - Tab loaders previously required an apiKey; now correctly treat "auth disabled" as authenticated (Android has no auth by default). - Re-trigger the active tab's loader after loadServerInfo resolves authRequired, since initTabs runs earlier. - Add i18n keys for the demo / mediaprojection / scrcpy_client engines. Docs: - TODO.md: follow-ups for multi-ABI wheel rebuilds, CI pipeline, USB serial LED controllers, root-only capture, perf metrics abstraction. - CLAUDE.md: Android dependency sync policy (pip --exclude doesn't exist).
