Add an optional positive-integer concurrency limit to workspace task settings and carry it onto resolved task nodes.
Reserve permits in the dependency-ready scheduler rather than inside workers. This lets unrelated task names use available workspace capacity, while tasks waiting on their own limit remain undispatched and do not start after a bailed failure.
Implement matching configuration validation, scheduling behavior, and integration coverage in the TypeScript CLI and pacquet.
Implements the per-task concurrency extension from pnpm/pnpm#14211.
