/**
 * `uxloom init` — one-command project setup, agent-agnostic:
 *  - registers the MCP server in ./.mcp.json (created or merged)
 *  - installs the agent skill for every agent layout found in the project
 *    (.claude/skills for Claude Code, .agents/skills for Codex; both when
 *    neither exists yet, so the repo is ready for either)
 *  - creates a starter uxloom.project.json if none exists
 * Never overwrites user content it didn't create; never touches git.
