* fix: support token auth for CLI SDK mock server to enable auto-model in smoke tests
- Add `advanced.debug.overrideAuthType` setting to control HMAC vs token
auth when overrideProxyUrl is set (default: HMAC for dev, token for tests)
- Update mock server model definitions to match real CAPI response shape
(family, vendor, version, supported_endpoints, billing, etc.)
- Add `selected_model` to mock `/models/session` response (required by SDK
auto-mode resolution)
- Add Responses API SSE handler for gpt-5.3-codex which uses `/responses`
instead of `/chat/completions`
- DRY up mock model definitions with shared `ALL_MODELS` array
* fix: add inspectConfig to test mock for copilotCliAuth and skip the other CLI smoke tests for now
* Don't run in PRs for now
