* fix: prevent empty reasoning messages in streaming interfaces
Prevents empty "Thinking..." indicators from appearing in clients by
filtering out reasoning messages with no content at the source.
Changes:
- Gemini: Don't emit ReasoningMessage when only thought_signature exists
- Gemini: Only emit reasoning content if text is non-empty
- Anthropic: Don't emit ReasoningMessage for BetaSignatureDelta
- Anthropic: Only emit reasoning content if thinking text is non-empty
This fixes the issue where providers send signature metadata before
actual thinking content, causing empty reasoning blocks to appear
in the UI after responses complete.
Affects: Gemini reasoning, Anthropic extended thinking

* feat: enable Datadog LLM Observability for memgpt-server
Enables DD_LLMOBS to track LLM calls, prompts, completions, and costs
in production for memgpt-server.
Changes:
- Add DD_LLMOBS_ENABLED=1 and DD_LLMOBS_ML_APP=memgpt-server in:
- .github/workflows/deploy-core.yml (GitHub Actions deployment)
- justfile (Helm deployment secrets)
- apps/core/letta/server/rest_api/app.py (runtime config)
This provides visibility into:
- LLM API calls and latency
- Prompt/completion content and tokens
- Model costs and usage
- Error rates per model/provider
