- Create ArtifactPill component (similar to SkillPill) - Renders filename as clickable pill with FileCode2 icon - Clicking pill opens artifacts panel and selects that artifact - Update ArtifactsToolRenderer to accept artifactsPanel reference - Pass artifactsPanel from ChatPanel to renderer on initialization - Display artifact pill below header for all commands - Pill only clickable when artifactsPanel reference is available
