feat(02-04): update all 5 adapters to use managed skills instead of static directories

- Claude: buildSkillsDir() accepts managedSkills, uses createManagedSkillSymlinks
- Codex: ensureCodexSkillsInjected() prefers managed skills over static scan
- Gemini: ensureGeminiSkillsInjected() prefers managed skills over static scan
- OpenCode: ensureOpenCodeSkillsInjected() prefers managed skills over static scan
- Kimi: new skill injection via ensureKimiSkillsInjected() (first-time support)
- All adapters fall back to static SKILLS_CANDIDATES when no managed skills provided
