Skill source paths for SkillsMiddleware.
List of paths to skill directories (e.g., ["/skills/user/", "/skills/project/"]).
When specified, the subagent will have its own SkillsMiddleware that loads skills
from these paths. This allows subagents to have different skill sets than the main agent.
Note: Custom subagents do NOT inherit skills from the main agent by default. Only the general-purpose subagent inherits the main agent's skills.
