igniterealtime/Spark ? reverse-engineered prompt

I want this turned into a working cross platform desktop chat client for businesses, something people on Windows, Mac, and Linux can actually install and use with an XMPP server, especially Openfire.

Please make sure the app supports the core experience shown in the project, one to one chat and group chat, tabbed conversations, file sending, screen capture sharing, inline spell check, message translation, and private end to end messaging with OTR. It should feel like a business friendly internal messenger, not a public social chat app.

Use the code that is already here, fix whatever is needed so it builds cleanly from source, launches reliably in an IDE or from the command line, and produces a usable distributable app. If there are missing pieces, outdated config, or broken dependencies, straighten that out too. If the project already has plugin support, keep that working.

Please also leave the repo in a state where I can clone it, build it, run it, and test login against an XMPP server without a bunch of manual guesswork. Look up current docs online if you need to.
