Add bounded login challenges, CSRF/origin enforcement, logout, and
session-bound WebSocket admission. Isolate private HTTPD access behind a
version-guarded adapter and add focused host coverage. Also let empty
admin
SSH input reach the normal console handler.
Add per-session history, tab completion, interactive prompts, and
bounded input handling. Support deferred lifecycle and host-key actions
after output drains, and document the expanded administration workflow.
Update validation and duplicate checks to scope key uniqueness per
account, and clarify the console error message. Document cross-account
key assignment and authentication testing.
