Two residual first-run gaps after the catalog model-defaulting fix:
- An active provider whose model has NO catalog default to fall back on
(custom openai-/anthropic-compatible endpoints) still bricked bare
`zero` and `zero setup` — the exact commands that could have repaired
the config. Tag that resolve failure with ErrProviderRequiresModel and
extend the interactive TUI's fixable-error fallback (previously only
ErrNoActiveProvider) to drop into the setup wizard for it. The sentinel
is attached via a message-preserving wrapper (multi-target Unwrap), so
headless commands (zero config / zero exec) print the exact actionable
text unchanged and every other resolve error stays fatal.
- `zero login` / `zero logout` don't exist (it's `zero auth login`);
first-run users try them and got only "unknown command" (reported in
the wild). The unknown-command error now answers: did you mean
"zero auth login"? Unrelated unknown commands get no suggestion.
Tests: the sentinel comes from a REAL Resolve over a real config file
(message-prefix asserted, no key leak); the TUI fallback is red-green
(reverting the condition reproduces the exact brick with the old error);
the existing no-active-provider fallback and other-errors-stay-fatal
tests still pass; login/logout hint with a no-false-positive check.
