chore(mcp): bump the local stack image to grafana/otel-lgtm 0.33.1 - Pyroscope 2.3.1, the image's healthcheck waits for the stack's ready marker

 Environment variables are the container's **only** configuration surface,

 reach it. This catalog is built from the pinned image's own tag —

+**`grafana/otel-lgtm:0.33.1`** (its README and `docker/run-*.sh`

 this file disagree, trust the tag.
