* refactor(auth): one sign-in flow behind SignInState, rendered by the CLI and the desktop
* feat(gateway): /signin signs the free tier into a Nous account from a DM
* feat(cli): chat surfaces name /signin as the sign-in verb
* fix(auth): review follow-ups for the shared sign-in flow and /signin
* fix(i18n): carry the /status free-tier line in every locale catalog
* refactor(cli): the chat sign-in command is /login
* fix(auth): durable override cleanup in the /login sweep, and the sign-in flow in its own modules
process_command resolves the canonical command (hermes_cli/commands.py registry)
to a handler via _slash_handler(): a 44-entry _SLASH_DISPATCH table for the
irregular cases (no-arg handlers, differently named methods, /exit and /update
return-value adapters) and the _handle_<name>_command(cmd) naming convention for
the other 47. Inline branch bodies became small _cmd_<name> methods; the
else-fallthrough (quick_commands -> plugins -> bundles -> skills -> prefix
expansion -> unknown) became _process_unregistered_slash. Pre-dispatch side
effects (pre_command hook, pending-resume disarm) and the False-exits-REPL
contract are unchanged. Also unifies the three random-tip blocks into
_print_random_tip and the repeated arg parsing into _slash_args; removes two
zero-reference helpers (_run_curses_picker, _try_launch_chrome_debug).
Parity guard: tests/cli/test_slash_dispatch_table.py asserts every command of
the old chain resolves and that no other registry command silently gained a
handler.
