Add a Market Gate node between the risk debate and Portfolio Manager
that verifies the target exchange is open before trade execution.
- New `market_gate.py` with `check_market_state()` and `create_market_gate()`
- Calls Headless Oracle /v5/demo (free, no API key required)
- Fail-closed: network errors default to UNKNOWN (blocked)
- Ticker suffix → MIC mapping for 22 global exchanges
- Injects [MARKET GATE] advisory into risk debate history
- Optional via `use_market_gate` config flag (default: True)
- 12 new tests covering MIC resolution, HTTP mocking, and node behavior
- Zero new dependencies (stdlib urllib only)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add effort parameter (high/medium/low) for Claude 4.5+ and 4.6 models,
consistent with OpenAI reasoning_effort and Google thinking_level.
Also add content normalization for Anthropic responses.
InvestDebateState was missing bull_history, bear_history, judge_decision.
RiskDebateState was missing aggressive_history, conservative_history,
neutral_history, latest_speaker, judge_decision. This caused KeyError
in _log_state() and reflection, especially with edge-case config values.
Prevents UnicodeEncodeError on Windows where the default encoding
(cp1252/gbk) cannot handle Unicode characters in LLM output.
Closes#77, closes#114, closes#126, closes#215, closes#332

- Integrate callbacks into TradingAgentsGraph and all LLM clients
- Dynamic agent/report counts based on selected analysts
- Fix report completion counting (tied to agent completion)
