CLI: add "Claude Agent (Max subscription, no API key)" to the provider
picker and register opus/sonnet/haiku model aliases so the CLI flow picks
up the provider registered in factory.py. No effort-level step since the
SDK doesn't expose that knob.
Analyst runner: build a concrete user request from company_of_interest +
trade_date instead of echoing the terse ("human", ticker) initial state —
the SDK was sitting idle on prompts like just "NVDA". Add opt-in file-
based debug logging (TRADINGAGENTS_CLAUDE_AGENT_DEBUG=1 → /tmp/...log)
for observability during long adaptive-thinking blocks.
Also adds main_claude_agent.py as a ready-to-run example for a Max-only
end-to-end invocation (verified 12-min NVDA run → SELL).

The 4 analysts (market, news, social, fundamentals) now detect a
ChatClaudeAgent LLM and dispatch to an SDK-native runner: LangChain @tool
functions are wrapped as in-process MCP tools via create_sdk_mcp_server, and
the SDK owns the iterative tool-calling loop. Claude returns the final report
in one call, so the analyst node outputs an AIMessage with no tool_calls and
the existing conditional edges route straight to the message-clear step.
Together with the Shape A provider this lets a Claude Max subscription drive
the full TradingAgents graph without an Anthropic API key. Other providers
continue to take the original bind_tools + LangGraph ToolNode path unchanged.
