https://hackmd.io/OULeRFQQQvaMURysN27eEw only the TestLifecycle integration test is updated with the new approach in this PR, to demonstrate that both old and new verb call strategies are still functional. will remove other usages of `ftl.Call(...)` to follow - generates `<Verb>Client` signatures in external stubs and (local) signatures in `types.ftl.go` - generates resource registrations in `main.go` and `types.ftl.go`, e.g. "providers" for verb clients -`go-runtime/build.go` changes accompanying the above^ bunch of stuff to get imports working now that we're generating full verb request/response types rather than just function references - updates `go-runtime/server.go` to inject the registered providers when processing an inbound call #2641 --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>

supply resources (DB, verb clients) to verbs explicitly— replacing ftl.Call(...), db.Exec(...) etc. (inspired by the pattern of injecting resources @stuartwdouglas implemented for the JVM)
need a way of knowing deterministically which resources a given verb uses. investigate/propose ways to accomplish this
