feat(cli): add ensureSubagentDefaults function to set default subagent configurations

This commit introduces the ensureSubagentDefaults function, which sets various default configurations for subagents, including max concurrent agents, max spawn depth, and run timeout settings. The function is called during the bootstrap process to ensure these defaults are applied for the specified profile.
