Issue: File Write Failure Due to Long URL Slugs in Page Cache

Description:
When caching pages with very long URL slugs, the generated cache file name exceeds the filesystem's maximum length (typically 255 characters), causing a "File name too long" error. This results in a 5xx error in Laravel.

Error Trace:

• silber/page-cache/src/Cache.php:158
  • The put() method calls the Filesystem’s put() method.
• Illuminate/Filesystem/Filesystem.php:204
  • The underlying file_put_contents() call fails due to the long file name.

Steps to Reproduce:

1. Enable the Silber page cache middleware in a Laravel application.
2. Access a URL with a slug longer than 255 characters.
3. Observe the "File name too long" error in the logs.

Expected Behavior:
The caching mechanism should handle long URL slugs gracefully, for example by truncating or hashing the slug, to ensure the file name stays within the allowed limit.

Proposed Solution:

• Modify the caching strategy to use a hashed or truncated file name.
• Alternatively, add configuration options for customizing the file naming strategy.

Environment:

• Laravel Version: 11.x
• PHP Version: 8.3
• Operating System: MacOS M4
