Mockup (illustrative) โ proposed per-project concurrency control for FR #608.
Host-wide ceiling across all projects. Protects the machine, not any single project.
Each project can cap its own concurrency below the workspace ceiling โ for heavier memory profiles.
The workspace cap still applies as an overall ceiling: a per-project value above it is effectively clamped by the workspace limit (no error). A project set to 1 runs strictly one task at a time.
