- map.test.ts: rewrite the fixture for region keys; the #6 regression guard now
proves the owner resolves via properties.regionKey while the repacked numeric
feature.id and the sub-region regionId do not.
- regions.test.ts (new): the loader sees 1,796 valid keys; FRA expands to its
42 sub-region keys (all valid, all labelled '… (FRA)'); allTerritoryKeys
unions correctly; and with no data it degrades to the raw input.
- engine.test.ts: buildUserPrompt includes a regions table only when provided;
applyTurnResult with a validKeys set applies real keys and ignores bogus ones,
and without one applies all (the legacy/unit path).
