irisandClaude Fable 5 56491f84b0 Follow the sibling project's rename to dev-updater
It is no longer "local" -- it serves over WireGuard rather than the LAN --
and it is specifically for developing new apps. Renaming the references
here at the same time keeps one name to search for across both repos.

Also drops the last references to gen-dev-cert.sh, which the in-process
certificate generation replaced: the build script and the Gradle task now
say to start the server once, and test-wg-tunnel.sh reads the
certificates from the XDG directory rather than the repo.

# The APK pins the CA on *this* machine ($XDG_CONFIG_HOME/ai-app/certs/ca.pem,
# or AI_APP_CA), so build it on the machine that runs the backend: an app
# built somewhere else trusts a CA that backend can't present, and simply
# won't connect. Start ai-server once first if there are no certificates
# yet -- it generates them; the build stops with that instruction if it
# can't find one.
#
# Unlike ./run-android.sh, this touches no emulator: it only produces the
# file. Installing on a real phone goes through Dev Updater, which serves
# whatever is under this project's build directory.
