Release v3.12.0
Summary
Rides the Chronicle 18.1.3 patch on top of main's migration to the 18 contracts (de5d934) and aligns the Host base image with it.
18.1.3 removes the 16.45 contract-surface restoration that briefly shipped in 18.1.1/18.1.2, so the client's descriptor no longer advertises services the kernel does not serve. The Host Dockerfile's cratis/chronicle base image tracks the same release, keeping the bundled kernel and the client from drifting apart (the drift the props file's own comment documents from 3.6.0).
