[UX] oclite: Tool calls rendered as noisy raw lines #63

Problem

During streaming, tool calls are rendered as individual lines like:

◇ bash
✓ bash
◇ rg
◇ task
✓ task
◇ check_task
✓ check_task

This creates visual clutter and makes the actual response text hard to find. Each tool invocation gets its own line with a status icon.

Expected

Tool calls should be rendered more compactly — either:

• A single updating status line: ⚙ Running tools (bash, rg, task)...
• Or hidden entirely, showing only the text response
• Or collapsed with a count: ✓ 12 tool calls completed
