* feat: add message_types filter to list messages endpoint
Add the ability to filter messages by type when listing message history
via GET /v1/agents/{agent_id}/messages. This brings parity with the
create message endpoint which already supports include_return_message_types.
Changes:
- Add message_types query parameter to list_messages endpoint in agents.py
- Add message_types parameter to get_agent_recall_async in server.py
- Filter messages by message_type after LettaMessage conversion
- Add test for message_types filtering
Closes#8277

* feat: allow client-side tools to be specified in request
Add `client_tools` field to LettaRequest to allow passing tool schemas
at message creation time without requiring server-side registration.
When the agent calls a client-side tool, execution pauses with
stop_reason=requires_approval for the client to provide tool returns.
- Add ClientToolSchema class for request-level tool schemas
- Merge client tools with agent tools in _get_valid_tools()
- Treat client-side tool calls as requiring approval
- Add integration tests for client-side tools flow

* test: add comprehensive end-to-end test for client-side tools
Update integration test to verify the complete flow:
- Agent calls client-side tool and pauses
- Client provides tool return with secret code
- Agent processes and responds
- User asks about the code, agent recalls it
- Validate full conversation history makes sense

V2 agent doesn't use client_tools but needs the parameter
to match the base class signature.

* 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:
