- Scale activity components (events, runs) to ~80% font size with
xs avatars for a quieter visual weight
- Hide succeeded runs from the timeline; only show failed/errored
- Always show three-dots menu on agent comments with "Copy message"
option, plus optional "View run" when available
- User avatar repositioned to top-right (items-start) of message
- Change "Me" → "You" in assignee labels for natural chat phrasing
("You updated this task")
