Behavior-preserving rewire: every per-ability code path now iterates the ordered ABILITIES registry instead of hand-enumerating the eight fields. - engine.ts: buildSystemPrompt (schema lines + constraint bullets), buildUserPrompt (payload keys at their historical positions), validateTurnResult (per-field validate), applyTurnResult (ordered apply block), isMeaningful, and the runTurn "unclear" fallback all drive off ABILITIES. The eight moved ability bodies (~1,249 lines) are deleted; the names the engine and its tests import are re-exported from ./abilities. - abilities/types.ts: Ability.stub is a zero-arg method (the stub has no GameState/AbilityCtx to pass; it needs none) — all eight implementations were already arg-less. - stub.ts: deterministicTurn fills the eight ability fields from the registry (each contributes its inert default), between the core fields and markers — JSON output stays byte-identical (verified against origin/master). - db.ts: the legacy-row migration for ability-owned GameState fields (wars/trades/embargoes/industry) iterates the registry's stateFields, only-if-undefined, instead of a hardcoded field list. No client changes, no new deps, no shared/ runtime deps. typecheck + lint + 511 unit tests green; stub JSON byte-identical to origin/master. Fixes #74
