Fix prefetch missing cacheFor default value

[talelmishali]

Fix prefetch method signature to match documentation

Description

Updates the prefetch method signature in router.ts to match the documented behavior by providing a default value for the cacheFor option. This fixes TS errors when calling router.prefetch with two arguments and aligns with the documented API.

Recreate

Calling router.prefetch to programmatically prefetch data like so:

router.prefetch(route('customers.show', row.original.id), { method: 'get' })

Results in TS2554: Expected 3 arguments, but got 2. and Uncaught TypeError: Cannot destructure property 'cacheFor' of 'undefined' as it is undefined. on runtime. This a result of not having a default value on the prefetch method on the router.

Changes

- public prefetch(href: string | URL, options: VisitOptions = {}, { cacheFor }: PrefetchOptions) {
+ public prefetch(href: string | URL, options: VisitOptions = {}, { cacheFor = 30 }: PrefetchOptions) {
