+Add zod v4 compatibility. The `zod` peer dependency is widened to `^3.25.0 || ^4.0.0`, so projects can use zod 3.25+ or zod 4. Internal code was updated for zod v4 API changes (`ZodError.errors` → `.issues`, single-arg `z.record` → keyed, unified `error` option, `z.ZodSchema`/`z.AnyZodObject` → `z.ZodType`/`z.ZodObject`, `z.any()` object fields made `.optional()` to preserve v3 inference). No runtime behavior change for existing zod 3 users.

+Upgrade the dashboard form layer from `@conform-to` 0.9 to 1.x. conform 1.x supports both zod 3 and zod 4, which unblocks the upcoming zod 4 upgrade.
