- New FeedUploader protocol with VFileUploader, GitHubUploader, CodebergUploader, WebDAVUploader - GitHub/Codeberg: fetch current file SHA via API before PUT (handles create + update) - WebDAV: HTTP PUT with optional Basic Auth - ComposeViewModel: always downloads from publicFeedURL (vfile token URL is upload-only, GET returns 404) - SettingsViewModel: per-method config fields + derived public URL hints for GitHub/Codeberg - SettingsView: method picker with conditional sections; VFile shows signup link; SFTP/FTP excluded (no native iOS support)
