ci: build and publish the apk from this repo

A package workflow on the pmos runner: pmbootstrap cross-builds the
aarch64 apk(s) from packaging/aport/ at the pushed commit and uploads
them to the Forgejo Alpine registry, so a daemon release reaches
installed phones via plain 'apk upgrade' without an fp6-img image run.
Releases are gated by pkgver: the registry 409s an already-published
version and the workflow moves on, so ordinary pushes are no-ops until
the aport bumps pkgver/pkgrel.

fp6-img is unchanged: images still build imsd from a pinned checkout of
this repo, from the same aport.

Needs the PACKAGE_TOKEN secret on this repo (or org-wide) to publish;
until then the workflow builds and skips the upload.

+# pkgver/pkgrel. fp6-img images keep building imsd from their own pinned
+# checkout of this repo; same aport, so the two pipelines cannot skew.

+# (catbot account, package:write scope) to publish; without it the build
+# still runs and the publish step skips quietly.
