fix: add video driver capability so NVENC works in the container

The Go-Live broadcast encodes with h264_nvenc, but the image only requested
NVIDIA_DRIVER_CAPABILITIES=compute,utility. The NVIDIA Container Toolkit gates
which driver libraries it injects by capability, and the NVENC/NVDEC libs
(libnvidia-encode.so.1 / libnvidia-decode.so.1) come with the `video`
capability. Without it the broadcast ffmpeg dies with
"Cannot load libnvidia-encode.so.1", the capture produces no packets, and
Go-Live never connects, while CUDA workloads (ollama/whisper/melo) and
nvidia-smi keep working because compute+utility are present.

Add `video` so hardware encode is available. Applies to both Linux (CDI) and
Windows Docker Desktop (WSL2).

+
+## Windows 11 notes
+
+- Install the NVIDIA driver on Windows and enable GPU in Docker Desktop
+  (Settings → Resources → WSL Integration). Use the `gpu-windows.yml` override.
+- Paths: named volumes are cross-platform. The Gemini OAuth login (for
+  `GEMINI_AUTH=oauth`) is bind-mounted from the project-local `./docker/gemini-oauth`
+  into the container's `~/.gemini`. A project-relative path is used so it resolves
+  the same on Windows Docker Desktop and Linux (`${HOME}` is often unset when
+  compose runs from PowerShell/cmd). Seed it once from a machine with a browser and
+  the logged-in Gemini CLI (`npm i -g @google/gemini-cli`, then `gemini` ->
+  "Sign in with Google"), copying the login state:
+  (Note: as of 2026-06 Google blocks personal Google accounts on this CLI login
+  with "This client is no longer supported for Gemini Code Assist for
+  individuals". Workspace/org accounts may still work; personal accounts should
+  use `GEMINI_AUTH=apikey` with a key from https://aistudio.google.com/app/apikey
+  instead. Real-time search fail-opens to DDG/Brave/Wikipedia either way.)
+  `cp -r ~/.gemini/. docker/gemini-oauth/`. The essential file is `oauth_creds.json`
+  (it holds the refresh token; `GOOGLE_GENAI_USE_GCA=true` forces OAuth, so that is
+  the file the startup readiness check looks for) - copying the whole dir simply also
+  carries the cached account/settings. To reuse an existing host login without
+  copying, set `GEMINI_OAUTH_DIR=~/.gemini` in `.env`. If unseeded, real-time search
+  fail-opens to DDG/Brave and the container logs a `🔑` warning on startup.
+
+## Known limitation
+
+Discord Go-Live broadcast of the **browser host's** screen from a **remote** bot
+is not supported (the bot's WebRTC screen capture is local to the bot machine).
+Use the browser host's VNC to view it. A full remote-broadcast path is separate,
+larger work.
