/**
 * bi-wheel-app.ts — MCP App tool registration for the Bi-Wheel Explorer.
 *
 * Registers 6 tools:
 *   • explore_bi_wheel               — primary entry point [model + app]
 *   • bi_wheel_recalculate           — re-fetch with new params [app-only]
 *   • bi_wheel_on_cross_aspect_click — cross-aspect click handler [app-only]
 *   • bi_wheel_on_planet_click       — planet click handler [app-only]
 *   • bi_wheel_on_house_click        — house cusp click handler [app-only]
 *   • bi_wheel_synopsis              — full reading overview [model + app]
 *
 * Supported modes (BiWheelMode):
 *   synastry     — two natal charts (person1 inner, person2 outer)
 *   transit      — natal inner + transiting planets outer
 *   progressed   — natal inner + secondary progressions outer  (POST /ephemeris/progressed)
 *   solar_return — natal inner + solar return chart outer      (POST /predictive/returns/solar)
 *   lunar_return — natal inner + lunar return chart outer      (POST /predictive/returns/lunar)
 *   solar_arc    — natal inner + solar arc directions outer    (client-side Naibod approximation)
 *
 * Cross-aspects are computed client-side (UI) AND server-side (for summary/fallback).
 * The payload cross_aspects array is capped at 30 tightest-orb aspects.
