better-auth default rateLimit config unusable with Cloudflare KV

[grrowl]

An annoying one for you. Cloudflare KV only supports KV TTLs >= 60s, but better-auth default rateLimit config now sets 10s as of better-auth/better-auth#4961

better-auth/better-auth#5452

You need to override the defaults or your app will crash all the time for auth routes:

{
    rateLimit: {
      enabled: true,
      window: 60, // Minimum KV TTL is 60s
      max: 100, // reqs/window
      customRules: {
        // https://github.com/better-auth/better-auth/issues/5452
        "*": {
          window: 60,
          max: 100,
        },
      },
    },
}

Should we consider adding Math.max(ttl, 60) and/or

console.warn(`[BetterAuthCloudflare] ttl ${ttl} is less than KV minimum of 60`)
