jaap-jan fe9d7fc289 Give DodoSSH a phone, and a shared shell for both heads to drive
The Android head from docs/android-port.md, taken as far as its step 6.

Step 3, the spike, is answered and its throwaway screen is gone: libsodium.so and
libe_sqlite3.so are both in the arm64 APK, so NSec resolves its native half on Android
despite shipping no Android build, and the local cache opens. Two findings the audit
could not have had: Avalonia.Controls.WebView only ships net10.0-android36.0, which
settles the open "which Android versions" question at targetSdk 36; and Android has
blocked cleartext HTTP since API 28, so the terminal renderer needs a network security
config scoped to 127.0.0.1 or the WebView loads nothing.

DodoSSH.Client.Shell is new and is why the phone can exist: the view models, the terminal
renderer files and the palette moved there so both heads drive one state machine and draw
from one set of tokens. The desktop head is otherwise untouched and its 144 tests still
pass.

The platform pieces behind interfaces that already existed: the profile directory from
filesDir, a device key wrapped by a StrongBox-backed key that a fingerprint releases, and
a foreground service so a shell outliving a vault lock stays true on a platform that
stops backgrounded processes.

Sign-in is deliberately absent rather than approximated. It needs an app link, because
reusing the desktop loopback listener is the attack RFC 8252 section 8.3 names.

Application-wide rather than on MainWindow, which is where the first three lived until the vault column
became its own control. A Window's styles reach its whole tree, so the move changes nothing about how
the application renders — but a control laid out on its own, as the layout harness lays the column out,
would otherwise lose them. That matters more than it looks: "hint" carries TextWrapping, and text that
wraps in the application and does not wrap in the harness makes every measured height too small, which
is the one way this kind of test lies quietly.

its own, so a Background set on the button is a TemplateBinding the theme's :pointerover rule overrides

Two states and not the design's three. Green means connected — a terminal is open on this host, or a

has an amber dot, which would have to mean "reachable but not connected", and nothing in this
application ever checks whether a host is reachable; a colour for a state nobody computes would be
decoration that reads as information.
A style rather than a value converter so that the two colours are the palette's, once. A converter
