Automatic cache invalidation for time-based content in TYPO3.

Addresses [TYPO3 Forge Issue #14277](https://forge.typo3.org/issues/14277):
Menus and content with starttime/endtime update automatically when time passes,
without manual cache clearing.

> [!IMPORTANT]
> **Extension Status**: Stable (version 1.0.2, state `stable` in
> `ext_emconf.php`). The API covered by [Public API](Api/Index.html#api) follows Semantic
> Versioning from 1.0.0 onwards.
>
> **Approach**: TYPO3's cache API has no absolute expiration, so the extension
> approximates one by shortening relative lifetimes or by flushing tags from a
> scheduled task. A solution inside TYPO3 core would need neither.
>
> See [Approach, limits and a core solution](Phases/Index.html#phases) for what the approach cannot do, and what core would have to
> provide to make the extension unnecessary.
