Add durable public-URL output and URL-based chaining to xAI Grok Imagine: - Store generated media on files-cdn with permanent public HTTPS URLs (public_url: true, no expiry by default). - Chain by URL: generate -> edit -> extend each take a prior result's public HTTPS URL (or a data URI / local file for inputs). - Add provider-specific xai_video_edit and xai_video_extend tools. - Image generation: public-URL/storage output, multi-reference edits, and ~/ local-path support for image edits. Credentials use xAI Grok device-code OAuth (separate PR).
