feat(games): add cloud-empress game package

Transcribe the six core-rulebook chapters into rules/, with every
rollable table extracted into tables/ so the CSVs are the single
source of truth: 21 tables plus the four starting kits under
characters/. Chapters keep only non-dice reference charts and the
age table.

Add eight commands: background, loadout, character, sigil, spell,
mishap, panic, and test (d100 under-roll with advantage and
disadvantage, including the doubles-as-extremes rule).

weather and encounters are package-authored stand-ins for the
setting-book tables; sparks and complication-themes are original.
