v0.12.3

[0.12.3] - 2026-06-22 - CLI polish + setup wizard UnboundLocalError fix

Bug fix

• minxg setup no longer raises UnboundLocalError: cannot access local variable 'run_setup'. The wizard's full-run dispatcher in
  multiligua_cli/main.py was named run_setup, which shadowed the
  same-named import inside main() and made the symbol local —
  the very first invocation from the CLI now hit the classic
  local-before-assignment trap. The dispatcher is renamed to
  cmd_setup, the @ensure_config decorator is removed (wizards
  don't need to recursively invoke themselves), and the resulting
  duplicated banner is dropped because the wizard prints its own
  rich panel. minxg model, minxg api, minxg key, minxg config,
  and minxg status were already fine — only the setup path was
  exposed.

CLI beautification

• Quiet by default. The Loading tool modules... and
  Registered N tools from new system INFO lines from
  multiling/orchestrator.py no longer print to stderr on every
  command. The logging root now starts at WARNING in interactive
  shells and is bumped to INFO only when minxg -v is passed
  (or MINXG_LOG_LEVEL=DEBUG is exported for diagnostics).
• Banner shows the real version. The header panel now reads
  MINXG — Five-Pillar Worker Platform v0.12.3 (the
  minxg.VERSION constant is rendered live instead of relying on
  whichever snapshot was last edited into the banner template).
• Setup wizard ribbon. The wizard banner gets a ◆ tagline vX.Y.Z
  accent line and a setup wizard sub-line so the user knows what the
  screen is for the moment they enter minxg setup.
• Step counter is correct. TOTAL_STEPS is now 6 (was 5), the
  duplicate step 2 of 5 for the mode prompt is now step 3 of 6,
  the orphaned step 7 of 5 for Browser Search is now step 6 of 6,
  and the dead-step step 8 of 5 Summary banner has been removed in
  favour of a non-step gold "Review your configuration" panel.
  setup_platforms (and the now-redundant comment) is documented as
  a compatibility shim so future readers don't think it ran.
• Wide-terminal-aware descriptions. Menu descriptions used to be
  hard-truncated to 28 characters. They now size themselves between
  28 and 56 based on shutil.get_terminal_size, so a desktop user
  gets the full provider description while Termux users still keep a
  single-line layout.
• Setup finishes with a celebration. _post_setup_hints now prints
  a centred ✓ Setup complete panel plus a two-column quick-reference
  grid (minxg, minxg gateway start, minxg doctor, …) so the
  first action after install is obvious.
