* feat: add built-in sub-agent presets with cross-platform export support

- Add general-purpose, explore, plan built-in sub-agent presets
- Export built-in agents as regular sub-agents for non-Claude Code targets
- Cursor export: readonly frontmatter for explore/plan, omit haiku model
- Non-CC prompt output: skip subagent_type, treat as normal sub-agents
- Rename controlledByCC to controlledByPreset across all translations
- Update builtInDescription to clarify behavior on other AI agents

- Use shared BuiltInSubAgentType instead of duplicated literal union

* improvement: prioritize built-in sub-agents in AI generation guidance

- Remove new agent auto-creation path from aiGenerationGuidance steps
- Add useCases and whenToUse for each built-in agent type (explore/plan/general-purpose)
- Remove list_available_agents from default AI editing flow

* improvement: slim down SubAgent schema section by 44%

- Remove verbose field descriptions (type/enum sufficient)
- Simplify builtInAgents to flat useCases arrays
