Sync fork with upstream TauricResearch/TradingAgents (v0.2.1) (#12)

* chore: remove unused chainlit dependency (CVE-2026-22218)

* fix: pass debate round config to ConditionalLogic (#361)

* fix: pass max_debate_rounds and max_risk_discuss_rounds config to ConditionalLogic

* use config values

* fix: add explicit UTF-8 encoding to all file open() calls

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

* fix: initialize all debate state fields in propagation.py

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.

* fix: handle comma-separated indicators in get_indicators tool

LLMs (especially smaller models) sometimes pass multiple indicator
names as a single comma-separated string instead of making separate
tool calls. Split and process each individually at the tool boundary.

* fix: add missing console import to cli/utils.py

Seven error-handling paths used console.print() but console was never
imported, causing NameError on invalid user input.

* fix: harden stock data parsing against malformed CSV and NaN values

Add _clean_dataframe() to normalize stock DataFrames before stockstats:
coerce invalid dates/prices, drop rows missing Close, fill price gaps.
Also add on_bad_lines="skip" to all cached CSV reads.

* chore: update model lists, bump to v0.2.1, fix package build

- OpenAI: add GPT-5.4, GPT-5.4 Pro; remove o-series and legacy GPT-4o
- Anthropic: add Claude Opus 4.6, Sonnet 4.6; remove legacy 4.1/4.0/3.x
- Google: add Gemini 3.1 Pro, 3.1 Flash Lite; remove deprecated
  gemini-3-pro-preview and Gemini 2.0 series
- xAI: clean up model list to match current API
- Simplify UnifiedChatOpenAI GPT-5 temperature handling
- Add missing tradingagents/__init__.py (fixes pip install building)

* docs: add v0.2.1 release note to README

* fix: add http_client support for SSL certificate customization

- Add http_client and http_async_client parameters to all LLM clients
- OpenAIClient, GoogleClient, AnthropicClient now support custom httpx clients
- Fixes SSL certificate verification errors on Windows Conda environments
- Users can now pass custom httpx.Client with verify=False or custom certs

Fixes #369

* Initial plan
