chore(meta): add orient skill and project README

Added /orient skill for lightweight context bootstrapping — reads
README.md, skill frontmatters, and mod structure without flooding
context. Added a lean README.md as the entry point for orientation.

+## Core Systems
+
+- **Allomancy** — Genetic trait system. Dormant potential activates via "snapping" into Misting types or full Mistborn.
+- **Lord Ruler Attention** — Variable (0–100) tracking defiance; escalating consequences.
+- **Compounding** — Allomantic + Feruchemical overlap triggers on yearly pulse.
+- **Hemalurgy** — Spike-based power transfer system.
