Subject: [PATCH] feat(display): show delegate_task goals in tool progress
 notifications

Previously, delegate_task in batch mode only showed '3 parallel tasks'
without revealing what the tasks actually are. Single-task mode showed
the goal via the primary_args fallback, but batch mode had no goal
extraction.

Changes:
- build_tool_preview(): Add dedicated delegate_task handler that
  extracts individual task goals from both single and batch modes.
  Batch shows '3 tasks: Goal A | Goal B | Goal C'.
- _get_cute_tool_message_impl(): Show individual goals in CLI cute
  messages for batch delegate calls ('3x: Goal A | Goal B').
- Add 4 tests covering single goal, batch goals, missing goals,
  and no-goal edge case.
