use either --app or --app-id/--app-secret, not both

Error message

use either --app or --app-id/--app-secret, not both

What it means

resolveFeishuSetupInputs normalizes credentials for `cc-connect feishu setup`. The --app flag takes an id:secret pair while --app-id/--app-secret take the halves individually; the two styles are mutually exclusive. This error is thrown when --app is combined with either half flag, preventing ambiguous duplicate credentials.

Solutions

1. Use only --app id:secret, or only --app-id X --app-secret Y
2. Remove the redundant --app flag if you intend to use the split flags
3. Remove --app-id/--app-secret if you intend to use --app

Example fix

// before
cc-connect feishu setup --app id:secret --app-id id --app-secret sec
// after
cc-connect feishu setup --app-id id --app-secret sec

if [[ -n "$APP" && ( -n "$APP_ID" || -n "$APP_SECRET" ) ]]; then echo "use --app or --app-id/--app-secret, not both" >&2; exit 1; fi

When it happens

Trigger: `cc-connect feishu setup --app id:secret --app-id id` or `--app id:secret --app-secret secret` (also after whitespace trimming).

Common situations: Migrating scripts from one flag style to the other and leaving both behind, or extending an existing command line with a second credential source copied from docs.
