Update reference docs: fix event names, add demos, document sx-boost target
- Remove sx:afterSettle (not dispatched), rename sx:sendError → sx:requestError
- Add sx:clientRoute event (Phase 3 client-side routing)
- Add working demos for all 10 events (afterRequest, afterSwap, requestError,
clientRoute, sseOpen, sseMessage, sseError were missing demos)
- Update sx-boost docs: configurable target selector, client routing behavior
- Remove app-specific nav logic from orchestration.sx, use sx:clientRoute event
- Pass page content deps to sx_response for component loading after server fallback
