vendor(cordis): document the full plugin-author surface (@param/@returns everywhere)

Comment-only enrichment across cordis/src/*.ts — Context, EventsService (+ the
ctx merges), Fiber, RegistryService, ReflectService, Service, logger — so the
website API generator can render a complete reference and hard-error on any
future undocumented member (vendor sync included). Logged as local
modification 6 in vendor/README.md; retire it when upstreamed to the fork.
INHERITED_SERVICES/EVENTS source pointers refreshed for the shifted lines;
cordis catalogs regenerated.
