rebrand: fix upstream attribution in README + Omnixient wordmark

 We're not actively syncing changes from TheArctesian/omnixy — the diff has grown large enough that the two projects serve different audiences now. If you only want the polished desktop, the original is the right place. If you want the dev environment, fleet deploy story, and aiolabs-specific tooling, this is.
