chore: release signage 0.1.3

0.1.3 ships the external package integration validated in #13 (Pass 2):
the canonical linux-x64-glibc Module Package installed and exercised
end to end by CI, with bounded external runtime image processing.

Only the version moves: the manifest, package.json, the server runtime,
both browser artifacts, the settings payload's moduleVersion, the test
fixtures, and the README status line. compatibility stays
platform ^0.2.0 and moduleSdk ^0.2.0; Core 0.2.4 already satisfies it,
so the range is not tightened. pnpm-lock.yaml carries no root version
and is unchanged.
