android-tier.md carried a warning block telling the reader not to use
run:device or deploy-device, and offered a manual sequence instead.
Both are wrong now: the tasks are the way in, and the warning would
read as a live hazard. It becomes a note about what changed, and the
manual sequence stays as the smallest thing that works when you want no
script between you and adb.

"The identity is declared twice" was the section this file had carried
for five phases saying nothing enforced that the two ids agree. It
describes the enforcement now, plus what APP_ID means since it stopped
being a setting it never was.

NOTES.md takes the four measurements: that the uninstall existed only
to cover a missing -r (which is what makes deleting it a fix rather
than a trade), that the emulator tasks installed on a phone, what
reading the id back costs, and the boot-wait race filed as #162.

logan 4b392cb4c4 fix(android): point the emulator script at the built APK's id
The third declaration of the app's identity, and the one #159 did not
cash out in: PKG defaulted to "app.yellowjacket" while
`make android-install` installs whatever is in bin/, which after
`wails3 task android:assemble:apk` is app.yellowjacket.dev. So
android-launch, android-logs and android-smoke addressed a package the
build had not produced, and the certificate-change message named the
wrong id to uninstall -- the release one.

It is derived from bin/yellowjacket.apk the same way the tasks are, so
it follows whichever variant was built last. YJ_ANDROID_PKG still
overrides, and the literal survives only for a tree with no APK yet,
where these commands are asking about whatever is already installed and
there is nothing to read.

cmd_inspect's probe order goes with it: "$PKG.dev" would append a
second suffix to an id that already carries one, so the candidates are
derived from the resolved id in either direction -- debug sibling
first, release second, as before.

logan 8d2109b87e fix(android): install and launch the package the APK declares
The four adb-driven tasks in build/android/Taskfile.yml began with
`adb uninstall {{.APP_ID}}`, where APP_ID defaulted to
"app.yellowjacket" -- the release id. `run` and `run:device` build the
*debug* variant, whose applicationIdSuffix makes it
"app.yellowjacket.dev", so both uninstalled the user's released app,
took the library with it, installed a different package, and then
failed to launch the one they had just removed.

The id is read back from the built APK now (scripts/android-pkgid.sh,
`aapt2 dump packagename`) rather than written down a second time, so
the thing installed and the thing launched agree by construction --
whatever Gradle resolved the applicationId to, suffixes included, is in
the file. An APK it cannot read is a hard failure and never a fallback
to a default; guessing is the bug. APP_ID survives with no default as
an *assertion*: it is checked against the artifact and refused, naming
both, before anything is installed or a target is even chosen.

The uninstall is gone rather than corrected. It was there to make the
bare `install` on the next line work at all -- Android refuses an
install over an existing package without -r -- so `install -r` removes
the reason for it. What is left is the one case an uninstall is really
the remedy, a changed signing certificate, and that is exactly the case
where doing it silently costs the user their library. So it is reported
with the command to run, which is the answer scripts/android-emulator.sh
had already reached for `make android-install`.

And the emulator tasks now say "emulator" to adb. A bare `adb install`
with one device attached picks that device whatever it is, so with a
phone plugged in and no emulator running, the task whose summary reads
"in the Android Emulator" installed on the phone -- the same data loss,
from the task whose name gives no warning. Several matching targets is
an error naming them rather than a silent pick of the first.

Closes #159
