Vellum 0.10.4

A feature release headlined by a memory system overhaul and rebuilt Slack rendering, plus plugins are now generally available.

• Self-improving skills. The assistant now writes its own skills based on memory, edits them, and knows what to do better next time. The retrospective writes and edits its own procedural notes, and recall is sharper for named people and things. The memory worker can be started, stopped, and checked from config.
• Richer Slack UI. Assistants now use native Slack images and tables instead of just sending plain text. Messages render through a real markdown parser, so images, tables, column alignment, and headings all work, and reactions show as emoji.
• Heartbeat on by default. A heartbeat is a moment when your assistant quietly checks in on its own, without you asking, to catch reminders, follow-ups, and anything time-sensitive. It's now enabled out of the box, with up to 10 runs a day. The Schedules tab gets shareable links to individual schedules.
• Improvements to default models. The managed Balanced profile moves to GLM 5.2 with medium reasoning effort. The Frontier profile is retired in favor of Quality. Together AI profiles now show topP and effort controls.
• Chat improvements. Fixed idle scroll flicker, and thinking and tool drawers now stay open after a turn finishes. Thinking previews now stream live as they generate.
• New plugins. You can install plugins directly from a GitHub URL, and the Plugins tab now matches the Skills tab. New in the plugin marketplace: Fitness Companion, Reading Pal, and Writing Coach.
