bithuman-cli 2.3.11

Turns the CLI into a guided experience: run/render with no key now auto-launch the browser sign-in inline and continue (CI/no-TTY unchanged); a new /v1/me pre-flight greets you and routes out-of-credit accounts to the upgrade page; auth failures are classified (out-of-credits → upgrade, bad key → re-login); doctor shows live plan + credits and now considers keychain/config creds (not just the BITHUMAN_API_SECRET env var); bare bithuman is an auth-aware welcome; and list/pull/info gently invite signed-out users to sign in. All nudges are gated to an interactive TTY, so pipes/--json/CI stay clean.
