feat(02-03): wire SkillService into ServiceGraph and preload bridge

- Add lazy SkillService creation in ServiceGraph with getOrCreateSkillService getter
- Pass skillService to registerDomainHandlers in main-runtime-support
- Add 7 skill operations to preload bridge (importSkill, listSkills, getSkillDetail, deleteSkill, assignSkillToAgent, removeSkillFromAgent, checkSkillUpdate)
- Add skillService cleanup in app lifecycle shutdown
