feat(headless): surface diagnostic monitoring data in non-interactive output

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

+# Prerequisites:
+#   Authentication must already be configured (API key, OAuth, or Vertex AI).
+#   Build the project first: npm run build
+#
+# Usage:

+# Options:
+#   --prompt <text>   Override the default test prompt
