Add Hermes control plane automation foundation

[chuckatbcs]

Summary

This PR adds a first foundation layer for running TradingOrg as a Hermes-controlled research and post-game review engine on the home PC.

Added

• AGENTS.md with repo-wide operating rules for AI agents.
• docs/HERMES_CONTROL_PLANE.md describing the Hermes/WebUI control-plane workflow.
• Non-interactive console scripts:
  • tradingagents-analyze-run
  • tradingagents-postgame
  • tradingagents-update-lessons
• Automation package under tradingagents/automation/.
• Hermes-safe scripts under scripts/hermes/:
  • run_single_ticker.sh
  • run_daily_watchlist.sh
  • run_postgame_review.sh
• Signal JSON output for automated runs.
• Deterministic post-game review JSON generation.
• memory/lessons.jsonl append workflow.
• .env.example updates for local Ollama, remote Tailscale Ollama, OpenRouter/free-cloud fallback, and premium fallback model settings.
• Docker Compose env and volume wiring for reports/ and memory/.

Changed

• DEFAULT_CONFIG now reads relevant LLM, routing, runtime, and data-vendor defaults from environment variables.
• OpenAI-compatible provider client now lets explicit base_url override provider defaults, enabling remote Ollama over Tailscale.
• Ollama model catalog now supports custom model IDs.
• .gitignore now excludes generated runtime outputs such as reports and JSONL lessons.

Safety boundaries

This PR does not add broker execution. TradingOrg remains a research/signal generator only. Generated signals include paper_only: true and an execution policy stating that the signal must not directly place broker orders.

Testing notes

Not run in this environment. Recommended local checks:

pip install -e .
python -m pytest tests -q
tradingagents-analyze-run --help
tradingagents-postgame --help
tradingagents-update-lessons --help
