Under wasm the guest has no network, so every Cal.com v2 call was dying at "dial tcp: lookup api.cal.com". Thread deps.OutboundHTTP (http.RoundTripper) from NewCalcomRouter onto CalcomHandler.rt and into NewCalcomClient, building the client with Transport: rt. A nil rt (native/DESCRIBE/test) falls back to the default transport, so bundled/httptest paths are unchanged. Declare allowed_hosts = ["api.cal.com"] (deny-by-default; admin-granted at install per the Phase 3 consent gate) and bump pluginsdk v0.2.4 -> v0.2.5 for CoreServices.OutboundHTTP. Bump 2.0.5 -> 2.0.6. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
