adfe5c4b44 Enforces config env var checks and improves startup handling (#892)
* Enforces config env var checks and improves startup handling

Ensures critical environment variables are validated during config resolution,
raising clear errors if missing. Improves server startup reliability by
verifying that backend services are listening and by terminating on
misconfiguration at launch. Adds more robust feedback to developers when
API startup fails, reducing silent misconfigurations and speeding up
troubleshooting.

* Initial plan

* Implement suggestions from PR #892: fix env var checks and improve error logging

faa422072c feat(subagents): make subagent timeout configurable via config.yaml (#897)
* feat(subagents): make subagent timeout configurable via config.yaml

- Add SubagentsAppConfig supporting global and per-agent timeout_seconds
- Load subagents config section in AppConfig.from_file()
- Registry now applies config.yaml overrides without mutating builtin defaults
- Polling safety-net in task_tool is now dynamic (execution timeout + 60s buffer)
- Document subagents section in config.example.yaml
- Add make test command and enforce TDD policy in CLAUDE.md
- Add 38 unit tests covering config validation, timeout resolution, registry
  override behavior, and polling timeout formula

* feat(subagents): add logging for subagent timeout config and execution

- Log loaded timeout config (global default + per-agent overrides) on startup
- Log debug message in registry when config.yaml overrides a builtin timeout
- Include timeout in executor's async execution start log
- Log effective timeout and polling limit when a task is dispatched
- Fix UnboundLocalError: move max_poll_count assignment before logger.info

* feat: add LangSmith tracing integration

Add optional LangSmith tracing support that can be enabled via environment
variables (LANGSMITH_TRACING, LANGSMITH_API_KEY, LANGSMITH_PROJECT,
LANGSMITH_ENDPOINT). When enabled, a LangChainTracer callback is attached
to chat models and run metadata is injected for trace tagging.

0ea666e0cf feat: add global memory mechanism for personalized conversations
Implement a memory system that stores user context and conversation history
in memory.json, uses LLM to summarize conversations, and injects relevant
context into system prompts for personalized responses.

Key components:
- MemoryConfig for configuration management
- MemoryUpdateQueue with debounce for batch processing
- MemoryUpdater for LLM-based memory extraction
- MemoryMiddleware to queue conversations after agent execution
- Memory injection into lead agent system prompt

Note: Add memory section to config.yaml to enable (see config.example.yaml)
