chore(release): bump the non-npm ports for 1.0.3

Maven Central `8.0.3` (npm major + 7, derived from scripts/maven-coordinate.mjs, not
typed), PyPI `1.0.3`, NuGet `1.0.3`. PyPI and NuGet were last cut at `1.0.1` and adopt the
shared `minor.patch` now current, skipping the number they sat out (ADR-0035 Amendment 1).

All four registries have changed product code this cut: npm carries FR-023 and the ADR-0055
reference implementation, and Maven / NuGet / PyPI each carry their ADR-0055 port, with PyPI
additionally carrying FR-023 Phase 1a.

The Java bump covers the two reactor-EXCLUDED integration-test modules and the showcase's
`<metaobjects.version>` — `mvn versions:set` walks only the reactor and would have left all
three behind. `scripts/check-pom-versions.sh` is green: 2 parent + 1 property pom match
reactor 8.0.3.
