TrajectoryRL

Reviewed overlay for SN11 TrajectoryRL using the official website, docs, leaderboard, live, winners, benchmark pages, and source repository. Common API/OpenAPI/Swagger paths currently return 404 and are not promoted as operational API surfaces. Two community-submitted surfaces (api-docs, subnet-api) had no probe config at all -- not disabled, just absent, meaning they were silently excluded from operational-surfaces.json / live health tracking despite being valid public endpoints (see #5932 for the registry-wide scope of this class of gap). Both confirmed live and given probe configs matching their sibling surfaces' conventions.
