Prepare Frame Control 0.2.0 for public testing

- Without the maintainer's key, Android compatibility reports stay on the
  Mac and the UI says so; the shared database is never contacted.
- Remove personal infrastructure details from scripts and docs: the Drive
  folder and gog wrapper now come from the environment, and the Chromium
  build host is required instead of defaulted.
- Add an MIT license, tester instructions in the README, and bump to 0.2.0.

 # Steam Frame ↔ Mac

+**Frame Control** is a Mac app for managing a Valve Steam Frame (standalone VR
+headset: SteamOS 3, Arch-based, arm64, Snapdragon 8 Gen 3) over SSH: live
+headset view, battery and status, your Steam library, Android (Lepton) apps,
+file and clipboard transfer. This repo also holds the scripts behind it and
+field notes on how the Frame's software works, all aimed at as little typing
+on the headset's virtual keyboard as possible.

-**Quick start:** set up SSH once (next section), then install
-[Frame Control](#frame-control-mac-app) from the DMG.
+## Trying it out
+
+You need:
+
+- A Steam Frame with **Developer Mode** on (next section; it's a toggle).
+- A Mac with Apple Silicon (M1 or later). Tested on macOS 26. There's no Intel
+  build.
+- `python3` on the Mac (`xcode-select --install` provides it).
+- Optional: `adb` for Android apps (`brew install android-platform-tools`).
+
+Steps:
+
+1. Download the DMG from the
+   [latest release](https://github.com/saphid/steam-frame/releases/latest),
+   open it and drag **Frame Control** to Applications.
+2. The app isn't notarized (no paid Apple developer account), so macOS will
+   say it's damaged or can't be checked. Clear the download quarantine once:
+   ```sh
+   xattr -dr com.apple.quarantine "/Applications/Frame Control.app"
+   ```
+3. Open it. With no `frame` SSH alias yet, it offers to run the connection
+   setup in Terminal. That asks for the Developer Mode password once, then
+   uses a key from then on.
+
+**Feedback:** please open a
+[GitHub issue](https://github.com/saphid/steam-frame/issues) with what you
+tried, your SteamOS build (Steam Settings → System) and the server log
+(**Frame → Show Server Log**, at `~/Library/Logs/Frame Control/server.log`).
+Features are marked **verified** or not below; the unverified ones are the
+most useful to hear about.
+
+**What it changes on your Frame:** only what you click. Installs go to your
+user account (`--user` Flatpaks, Lepton instances, Steam downloads), and
+nothing needs `sudo` except the power buttons. On the Mac it adds a `Host
+frame` entry to `~/.ssh/config` and a key at `~/.ssh/id_ed25519_frame`.
