slog TestHandler proposal routes logs to testing.TB

A proposal lands to add a slog.Handler to the standard library that writes through testing.TB's Output method, so test logs end up where the test framework expects them rather than scattered across stderr. Small surface, but the kind of papercut that quietly accumulates across a codebase. Over on r/golang, a thread asks what people are actually building with all the agent frameworks that have dominated Go conference schedules for two years running, which is a fair question to put on the table. Adjacent to that, a golang-nuts post pitches a Trivy-based security standard aimed at the reality of Go services that are increasingly AI-generated. On the writing side, a walkthrough of an in-house API gateway called Conduit covers stitching three microservices with mismatched auth behind one public endpoint, and a production post-mortem revisits the goroutine leak pattern that keeps showing up in services whose dashboards look fine right up until they don't.
