/**
 * Bug #2419: gsd-project-researcher agent type not found
 *
 * When gsd-new-project spawns gsd-project-researcher subagents, it fails with
 * "agent type not found" if the user has a local-only install (agents in
 * .claude/agents/ of a different project, not the global ~/.claude/agents/).
 *
 * Fix: new-project.md and new-milestone.md must parse agents_installed from
 * the init JSON and warn the user (rather than silently failing) when agents
 * are missing.
