Diagnostic monitoring data (auth_method, user_tier, api_requests,
api_errors, retry_count, RETRY events, LOOP_DETECTED events, and
stderr warnings) is now only emitted when --debug / -d is passed.
Without the flag, headless output is identical to before — no new
fields, no new events, no stderr noise. This keeps default output
clean for piped workflows while making diagnostics available on demand.
When running Gemini CLI in headless mode (-p), critical diagnostic data
like auth method, API retry attempts, loop detection, and request stats
was invisible despite being tracked internally. This change surfaces
that data across all three output formats (stream-json, json, text).
Changes:
- Add RETRY and LOOP_DETECTED event types to stream-json output
- Include auth_method and user_tier in init events and JSON output
- Add api_requests, api_errors, and retry_count to result stats
- Track and expose detected loop type (tool call, chanting, LLM-detected)
- Emit [RETRY] and [WARNING] messages to stderr in text mode
- Listen to CoreEvent.RetryAttempt in non-interactive CLI
- Add test script (scripts/test_gemini.sh) for manual verification
