Lazy-load Light and Sun analysis hooks

[elkimek]

Summary

• keep Sun context available during startup while deferring the Light/Sun analysis and feature-hook group behind one cached loader
• initialize the lazy group before Light routes, optional interactive Light dashboard widgets, assessment modals, session analysis, and direct session-modal access
• make route completion awaitable, preserve sync/async channel navigation, and avoid rendering hidden dashboard widgets
• regenerate the module map, document the boundary, bump the app version, and add loader/route/widget browser coverage
