[Bug] Tools render inline with prose instead of on new lines #101

Problem

Tools are rendering inline with prose text instead of on separate lines:

most impactful  ones first.  ◇ bash  gh issue create --title "fix(db)...

Should be:

most impactful ones first.

◇ bash  gh issue create --title "fix(db)...

Cause

The Live Block tool rendering doesn't force a newline before tool output when prose text is still being streamed.

Files

• packages/opencode/src/cli/lite/liveblock.ts
• packages/opencode/src/cli/lite/index.ts

Acceptance Criteria

• Tools always render on their own line
• Newline inserted before tool if prose text precedes it
