Relocate the conic intersection calculator from standalone rConic module
into rTrips at /routes sub-page. Adds enhanced visualization with ghost
conic curves, distinct arc colors, overlap zones, crossing angle lines,
pulsing intersection markers, arc labels, and SVG legend.
- New math: sampleConicCurve() for ghost curve tracing, conicTangentAt()
for tangent/crossing angle computation
- Route planner served at /{space}/trips/routes with OSRM proxy
- Removed standalone conic module registration from server/index.ts
- Updated vite build config to build folk-route-planner under trips
