fix: narrow E501 ignores and add ruff/pytest dev dependencies

- Replace broad tradingagents/**/*.py E501 ignore with targeted
  per-file ignores for agent files (LLM prompts), alpha_vantage_indicator,
  y_finance (description strings), and reflection (prompt constant)
- Fix the two genuine logic-code E501 violations: break long log message
  in stockstats_utils.py and ternary in yfinance_news.py
- Correct pytest version bound to >=8.3.0 (stable floor)
- Add ruff>=0.9.0 as dev dependency for local linter execution
