v0.2.3

What changed

Removes the stale explicit "version" field from composer.json. With that field present, composer's VCS driver reported every git tag as the same version (0.2.0), so consumers resolving nr-repurpose from the VCS repository received the oldest tag — and thus the pre-0.23 nr-llm constraint — instead of the latest. Git tags now drive the package version.

Combined with v0.2.2 (nr-llm 0.23 CompletionServiceInterface support, guides.xml repair, docs render CI), this makes ^0.2 correctly resolve to the current release on the nr-llm 0.23 line.

Additive 0.x patch.
