Make the final reply always visible and fix artifacts-panel dead clicks

Why: field report two — the final answer collapsed into the process
area (the CF0 long-reply fold swallowed 2000+ char replies and the
model inlines narration, so users saw "everything folded") and the
artifacts workspace panel preview clicks did nothing (the full-screen
overlay stayed up, hiding the rail the preview opened in).

Evidence:
- Conversation.tsx: removed the CF0 LongReplyCollapse entirely — the
  final output contract is "the reply to the user is always fully
  visible; only process parts fold"; deliverable cards stay pinned
  after the reply
- Workspaces.tsx ArtifactsPanel: row click and fullscreen action now
  close the workspace overlay before requesting the rail/fullscreen
  preview, so the preview is actually on screen
- vitest 40/40, tsc clean; no design-guard regressions (no new colors,
  keyframes, or inline font sizes)

Impact: replies are readable in place; ⌘1 panel clicks visibly open
previews; no other surfaces changed.
