feat: purge related File/Image URLs on page and DataObject cache invalidation

[Sitetools]

Hi. We are evaluating catalyst/silverstripe-cloudflare for some projects where we need Cloudflare purging support not just for page publish/unpublish events, but also for File publish/unpublish events, including variants.

We are considering contributing this upstream. Before doing that, we wanted to check whether you would be open to a PR that adds asset-level purging, and whether you are intending to support Silverstripe 6 in the near term.

For us, SS6 support is important, so ideally we would want confidence that any PR would be reviewed and that there is a path to getting it released in an SS6-compatible version.

If this is of interest, we're happy to outline the proposed approach before starting.

Hi again, just following up as we (Springtimesoft) haven’t heard back yet.

Given our timelines, we’re planning to move ahead by forking the project, upgrading it to Silverstripe 6, and implementing the asset-level Cloudflare purging support we described (including File publish/unpublish events and variants).

Our intention would then be to raise a PRs back to this repository with those changes, so you’re welcome to review and adopt them if they align with your roadmap.

If you have any preferences, guidance, or plans around Silverstripe 6 support that we should be aware of before we proceed, we’d still really appreciate your input.

Thanks!

Hi, I think the feature/6 branch is compatible with SSv6 , no ?
