ADR 0275, to-be 53: the issue tracker's module is mesh-issues, holding the seat issue-tracker

The operator named the module on 2026-10-10: the mesh's own parts carry the
mesh- prefix, and the seat is the role. A dated insight in ADR 0275 says so,
and that compare-and-set state was already in the runtime (ADR 0259): slice 1
added the SDK's Increment. To-be 53 and the glossary say the same, and the
design is handed to mesh-catalog and mesh-sdk (in progress).

 ## Consequences
 
 - Collisions end at the source: a number is taken from one counter, not read from a repository many branches write.
