crew v0.1.1 — skill-aware agents

crew agents are now skill-aware. Each agent that can act on one carries the Skill tool and invokes the skills its role turns on:

• coder, quick — run the ponytail:ponytail laziness ladder before editing; pull in a design skill (make-interfaces-feel-better, emil-design-eng, apple-design, animate, dataviz) on UI, motion or chart work.
• planner — holds the plan to the ponytail ladder and the same design skills.
• architect — reaches for dataviz and the design skills when a cross-subsystem plan lands in the UI.
• reviewer — runs code-review, security-review and break-ui.
• scout — left alone; a read-only locator has no skill to lean on.
