[UX] oclite: Rich tool call display with context and results

[randomm]

Description

Show tool calls with meaningful context — what tool, what input summary, and a brief result — instead of just the tool name.

Target UX (from sketch)

● Teammate(send message to: views-builder: "Task #1 is complete! The foundation is ready at m...")
  Message sent to views-builder's inbox

● Teammate(request shutdown: foundation-builder)
  shutdown request sent to foundation-builder

Current behavior (after #63 fix)

bash ✓ rg ✓ task ✓

Compact but lacks context — user doesn't know what the tools did.

Requirements

• Show tool name with input summary (first ~80 chars)
• Show tool result below (indented, dimmed)
• Color-coded bullet: ◇ pending, ● completed, ✗ failed
• Collapsible for long outputs
• Different display for different tool types:
  • bash: show command
  • read/write: show file path
  • task: show agent + description
  • rg/glob: show pattern

Data available

The tool_start and tool_end chunks already include tool, input, and output fields in session.ts.

Files

• packages/opencode/src/cli/lite/index.ts — tool chunk rendering
• packages/opencode/src/cli/lite/session.ts — chunk data
