Initial release v0.1.0

Home Assistant custom integration for NVIDIA Shield TV that composes
the Android TV Remote, Jellyfin, smart plug, and receiver entities
into a single unified media player with ADB-based now-playing from
any app. Part of the Media Zone ecosystem.

Entities:
- media_player: power (with smart plug fallback), transport, input,
  volume routed to receiver, rich stream info overlay when Jellyfin
  is active
- sensor: DAG attributes and stream info
- button: Pair ADB

Config:
- Two-step flow: basic setup + optional ADB pairing on the Shield
- Configurable ADB port (default 5555)
- Pick an existing Jellyfin media_player entity — stream info is read
  from the HA Jellyfin integration's own DataUpdateCoordinator, so
  no server URL / API key / extra config needed here
- Privacy mode (adb_store_app_info=False) suppresses non-Jellyfin
  media details, showing only the app name

Ecosystem:
- Exposes media_dag_* attributes for ha-media-zone orchestration
- Exposes media_dag_running_apps and async_bring_to_foreground for
  the Media Zone card's app switcher

Shared ADB code lives in ltomes/ha-adb-common and is vendored at
custom_components/nvidia_shield/ha_adb_common/ for HACS installs.
