Add PortfolioAnalyzer class that runs the full agent pipeline on multiple
stocks and produces a comparative KEEP/REDUCE/EXIT recommendation using
the deep thinking LLM. Includes per-ticker error handling, graceful
degradation on LLM failure, and result logging.
Addresses #60 and partially #406.

Add effort parameter (high/medium/low) for Claude 4.5+ and 4.6 models,

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
