[ENH] Adding snikket server doap and make it properly listed on xmpp.org

[marcellintacite]

Summary

This MR adds a DOAP (Description of a Project) file for Snikket Server and updates its entry in the software database to enable proper listing in the main filterable software directory on xmpp.org.

Changes Made

• Created static/hosted-doap/snikket-server.doap with comprehensive project metadata
• Updated data/software.json to reference the new DOAP file instead of null

Technical Details

• Added complete DOAP XML with project description, homepage, repository, and platform information
• Updated platforms to reflect actual supported operating systems (Linux, macOS, Windows)

Impact

• Before: Snikket Server only appeared in the collapsed "Other Software" section
• After: Snikket Server now appears in the main filterable software list with rich metadata
• Users can now filter and search for Snikket Server alongside other XMPP servers
• Improved discoverability and professional presentation of the project

@mwild1 should Snikket be listed at all? I was under the impression that it shouldn't be listed, but I might remember that wrongly.

I don't object to it being listed somewhere on xmpp.org, but indeed, I don't think the current XMPP server list is the right place for it. Snikket is more like an "opinionated XMPP distribution", or a "product that uses XMPP".

For example, this PR focuses on listing the server part of Snikket. But it is not really equivalent to Prosody, ejabberd and Openfire which are all generic XMPP servers. If you list Snikket in the server section, why not also list it in the client section? Except people might then expect to be able to use the Snikket app without the Snikket server (not really supported).

I don't know what the best answer is, but I don't want to advertise Snikket as something equivalent to Prosody/ejabberd/etc. and get lots of people asking how they can configure (for example) a pubsub component or IRC gateway with their Snikket server - things that Snikket intentionally does not support, but other XMPP servers do. It's just a different thing.

Snikket should be in the active list because it is actively supported/developed.

Ok, let's create a new category name. "Integrated platform"? Or have a new "Other" section and add info like "Opinionated XMPP distribution" in the description. Perhaps we should link to https://snikket.org/faq/ so any visitor gets a thorough overview to determine if it's a good fit for them.
