/**
 * transit-timeline-app.ts — MCP App tool registration for the Transit Timeline.
 *
 * Registers 1 tool:
 *   • explore_transit_timeline — primary entry point, returns data + UI resource.
 *
 * The tool mirrors the `ephemeris_transits` plumbing: it computes the natal
 * chart to extract real planetary longitudes, searches predictive transits
 * against those targets, then flattens the (planet@target → hits) result map
 * into a single chronological array the iframe renders as a vertical timeline.
 *
 * Also exports resource helpers (getTransitTimelineBundle, etc.) for use in
 * index.ts and server-sse.ts.
