+spec: add `defineX` factories for the remaining 16 writable domains and the 6
+missing `XInput` aliases — one consistent, type-safe authoring entry per domain
+(#2035).
+
+New factories: `defineDatasource`, `defineConnector`, `definePolicy`,
+`defineSharingRule`, `defineRole`, `definePermissionSet`,
+`defineEmailTemplateDefinition`, `defineReport`, `defineWebhook`,
+`defineObjectExtension`, `defineCube`, `defineMapping`, `defineTheme`,
+`defineTranslationBundle`, `definePage`, `defineAction`. Each mirrors the 19
+existing factories (`XSchema.parse(z.input<…>)`): input-shape ergonomics +
+authoring-time validation. Because a factory is a *value* import, a broken
+import hard-errors instead of silently degrading to `any` (the #2023 failure
+mode), and errors surface at `.parse()` time with field-level messages.
+
+Also adds the previously-missing input aliases `PolicyInput`, `CubeInput`,
+`MappingInput`, `ThemeInput`, `TranslationBundleInput`, `PageInput`.
+
+Purely additive: no existing exports change.
