Auto Extend the cached file's longevity if the user views it before it expired.

## Auto Extend Longevity (Maybe Boolean)

an option to auto-extend the cached file's expiration date or longevity.

### Contextualize the feature
It would be great, since, for example, like my application, I want to extend the longevity of a cached file every time a user views it. So, that it wouldn't cost me a lot with database: Bandwidth.

### Describe the feature
Maybe add an option to enable the auto-extend longevity option, so that every time a user views a file its longevity time is extended. For example, I've set my file's longevity to 3 days. If the user views this file on day 2, a day before expiration, the expiration date will be extended by 2 days. Now the file would expire 3 days after the user viewed it. It would continue extending the expiration date and longevity unless a user hasn't viewed this file for 3 consecutive days.

This would help greatly if the application we're implementing it in is a social media type or e-commerce. We can cache the images and auto-extend their expiration date every time a user views them. But please make sure that the file is removed after the expiration date is over.

No files, tests, or entry points are identified. Start by locating the cache expiration and eviction paths in the repository, then resolve the option's API and renewal semantics. Done means viewed files renew their lifetime while unviewed files are removed after expiry, with tests covering both behaviors.
