Subject: [PATCH] feat: extend hover copy button to tool results and
 intermediate AI text

Follow-up to bff0910 which added a hover CopyButton to the text variant
of LastOutputDisplay. Two more surfaces in the chat view show copyable
prose and benefit from the same affordance:

- LastOutputDisplay tool_result block: adds an inline CopyButton in the
  header row (right-aligned next to the tool name / error badge)
- TextItem: passes copyable to MarkdownViewer so intermediate AI text
  outputs (inside the expanded view of an AI group) get the same hover
  copy button that ThinkingItem already has

No behavior change to selection logic; both are always-visible affordances
matching the existing CopyButton pattern.
