feat: add decision calibration, prediction tracking, and reference routing

SKILL.md
- Add triggers/mode to frontmatter for better skill routing
- Add mandatory JSON decision skeleton before every trade
- Add multi-source confirmation rule and common-mistakes guardrails
- Add prediction logging to hourly review workflow
- Restructure References into an explicit routing table

CLAUDE.md
- Add Reference routing table for agent context
- Fix remaining Hermes-only wording in gate description

references/user-data-layout.md
- Add complete log schema: decisions, trades, predictions, errors
- Document predictions_YYYYMMDD.jsonl for calibration feedback loop

README.md
- Mention prediction tracking in "Why it works"
- Update runtime directory layout to include predictions.jsonl

references/shim-templates.md
- Show platform cron config usage examples

 - **Portfolio-first rule** — every decision anchors to your real balances, average costs, and exchange state.
 - **Scientific checklist** — 6 mandatory questions (trend, volume, levels, BTC context, opportunity cost, time window) before every trade.
 - **Hourly self-review** — the bot critiques its own decisions, flags over-trading / hesitation, and tunes parameters.
+- **Prediction tracking** — every decision writes an auditable prediction to `logs/predictions_YYYYMMDD.jsonl`; the review loop scores accuracy and surfaces systematic bias.
 - **Ultra-low running cost** — a lightweight local **gate** filters noise; the LLM only wakes up when the market actually changes.
