Re-enable exactOptionalPropertyTypes (#1271)

obiot · claude · web-flow · commit 66e61bbad353 · 2026-04-14T11:15:21.000+08:00
Upstream type issues in vite, vitest, and @types/node are now resolved.
The only remaining error was in gamepad.ts where ButtonBinding.threshold
needed `| undefined` added to the optional property type.
