Subject: [PATCH] feat(kernel): increase inotify limits for user
 instances/watches

Set higher limits for `fs.inotify.max_user_instances` and `fs.inotify.max_user_watches` in the kernel sysctl configuration. This improves system monitoring capabilities, particularly for applications relying on inotify.
