2. Better resource utilisation

Non-goals

Background

If I want to use turbo dependency tree and run a few tasks in parallel in workspace module (not in root: turbo run type-check lint format), that child turbo call would be treated as a separate process. So prefixes are added in stream or sidebar doubled in tui.

PS, relates to: #9923

Proposal

if turbo meets other call of turbo, add it's tasks to the main queue
