/**
 * moon-phase-app.ts — MCP App tool registration for the Moon Phase Explorer.
 *
 * Registers 1 tool:
 *   • explore_moon_phase — primary entry point, returns data + UI resource [model]
 *
 * The dial is rendered client-side from structured JSON. The tool calls the
 * existing moon phase and VOC endpoints, merges the results, and returns them
 * with a UI resource link so the iframe can render a circular phase dial.
 *
 * Also exports resource helpers (getMoonPhaseBundle, etc.) for use in
 * index.ts and server-sse.ts.
