/**
 * `openlore env-impact` — the env-impact tool's CLI surface
 * (change: add-env-config-impact-graph).
 *
 * Prints what breaks if an environment variable is removed or renamed (the same
 * conclusion the `analyze_env_impact` MCP tool returns) so a developer can answer
 * "what reads this, and what is the blast radius?" without an MCP client.
 * Read-only, deterministic, offline, never blocks.
 *
 *   openlore env-impact --name DATABASE_URL
 *   openlore env-impact --name PORT --max-depth 5
 *   openlore env-impact --name SECRET_KEY --json
