new mode does not accept credentials; use `cc-connect feishu

Error message

new mode does not accept credentials; use `cc-connect feishu bind`

What it means

New mode creates a brand-new Feishu app, so pre-existing credentials are meaningless and rejected. resolveFeishuSetupInputs throws this error when `--mode new` is combined with --app or --app-id/--app-secret, directing the user to the bind subcommand instead.

Solutions

1. Drop the credential flags when using --mode new
2. Use `cc-connect feishu setup --mode bind --app id:secret` (or the bind subcommand) if you want to reuse the existing app
3. Remove credential interpolation from the script invocation when mode is new

Example fix

// before
cc-connect feishu setup --mode new --app-id id --app-secret sec
// after
cc-connect feishu setup --mode bind --app-id id --app-secret sec

if [[ "$MODE" == new && ( -n "$APP" || -n "$APP_ID" || -n "$APP_SECRET" ) ]]; then echo "new mode takes no credentials" >&2; exit 1; fi

When it happens

Trigger: `cc-connect feishu setup --mode new --app id:secret` or `--mode new --app-id X --app-secret Y`.
