## What changed
- Add `--chatgpt-token-stdin` for remote HTTPS registration and optional `--chatgpt-account-id`, which must match the token's account claim when present. Read a bounded, newline-terminated token from a pipe without persisting it to `auth.json`.
- Load managed configuration using the supplied account, enforce account restrictions, and preserve configured policy-server authentication. Skip ChatGPT policy lookup only for known plans that do not require managed configuration.
- Allow `--exit-on-stdin-close` to cancel pending policy loading, and redact the registration bearer from registry diagnostics.
- Reject incompatible stdin credential options, including flags placed on opposite sides of `forward`, and disallow ChatGPT token stdin authentication with `forward`.
## Testing
Add coverage for account-claim validation, policy selection, policy-server sign-in requirements, shutdown during policy loading, credential flag conflicts, and bearer redaction.
