nx_http_router.nx

nx_http_router.nx -- method+path route dispatch table. Final missing piece for porting an Elder AI service to NishiLang. Existing substrate: nx_http.nx -- request parser (64-header HttpRequest struct) nx_http_io.nx -- minimal server-side parse + write nx_http_resp.nx -- response builder nx_http_client.nx -- HTTP client (outbound) nx_http_date.nx -- date formatter nx_syscalls + nx_syscalls_x86_64 -- socket bind/listen/accept This module adds the dispatch layer: a Route table of (method, path_pattern, handler_id) triples, and a match function that returns the handler_id for an incoming (method, path). NishiLang doesn't have first-class function pointers, so the caller dispatches on handler_id via switch-style if/else chain. Same pattern Flask + Express + FastAPI use internally before the reflection layer. Path matching v1: exact match or prefix match (controlled per-route). Path parameters (e.g. /api/character/:id) queued for v2 -- v1 routes match prefix and let the handler peel the remainder. genealogy_id: flask_routing + express_dispatch + actix_web_routes lineage_id: substrate_http_router_v1
