Grok Build 1.0.9 Adds Workflow Controls

This is a meaningful quality-of-control release: parallel agents become far more useful when developers can budget, tune, and reuse them. The challenge now is pairing plugin convenience with strong permissions and observability.

• –Child-agent budgets can limit runaway fan-out and control workflow costs.
• –Adjustable reasoning effort lets developers reserve deeper thinking for complex phases.
• –Name-based discovery turns saved workflows into reusable capabilities agents can compose.
• –Plugin agents gaining first-class visibility makes Grok Build more extensible, but increases trust and permission concerns.
• –The direction is clear: Grok Build is becoming an agent orchestration layer, not just a coding assistant.
