Build the phone in a container, because this runner cannot build it at all
The runner is Alpine, and .NET for Android does not work on musl. Not "needs setting up" — the SDK's
own MSBuild tasks pull glibc shared objects out of the workload pack into the build process, and a
musl-linked dotnet will not load one:

  error XARLP7000: Error relocating .../libZipSharpNative-3-3.so: __snprintf_chk: symbol not found

That is a glibc fortify symbol musl does not implement, reached through a DllImport rather than an
exec, so gcompat is no help: it gets a glibc *executable* started, which is a different problem. There
is no musl variant of the pack.

Everything this job did on the host to make Android work was therefore treatment of symptoms, mine
included. The missing aapt2 was present. The "unsupported version" was of a binary that had never run.
Both were this one sentence in a different accent, and the loader was the accent, not the sentence.

So the toolchain moves into build/android-build.Dockerfile — Microsoft's own sdk:10.0-noble plus a JDK,
the Android SDK and the workload — and the job keeps on the host only what the host is good at:
checkout, git, publishing. The daemon needed no arranging, since the image job already builds with it
and every Testcontainers suite reaches it over the socket. The image is tagged by the digest of the
Dockerfile that made it, so on a persistent runner every run after the first is a cache hit, and a
change to the toolchain is the only thing that buys a new one.

Built rather than pulled: a community image with the Android SDK already in it would put a stranger in
the path of a package this project signs and publishes. Eleven lines of apt and sdkmanager is the
cheaper trade.

Verified end to end in that image against a real clone rather than reasoned about, which after three
rounds of reasoning seemed the least I could do. Restore under locked mode, Release build, then
SignAndroidPackage:

  package: name='dev.dodotech.dodossh.nightly' versionCode='195' versionName='0.0.0-alpha.0.128'
  Signer #1 certificate SHA-256 digest: a9f067877724ddb0fdc04b637fbd5bfb97df753976616f100b48b522e132ba22

which is the keystore in build/. The versionName carries MinVer's height, so the csproj's target fires
in the container too, and the manifest the feed publishes parses back on the host.

Staging moves from RUNNER_TEMP to artifacts/, which is forced rather than preferred: the package is
made inside a container and read outside one, so it has to land under the bind-mounted checkout.
