Subject: [PATCH] chore: announce the rename from the image itself, and stop
 rebuilding

ghcr.io/widgrensit/asobi_lua is the old name for what is now
ghcr.io/widgrensit/asobi. The Lua runtime stopped being a separate
application when it merged, so the name described a part rather than the
whole, and this repo has held no source of its own since.

The risk in retiring a tag is silence: stop publishing and :latest simply
freezes, with nobody told. So the last build says so on every start,
where an operator will actually meet it - the image is renamed, tags
already published keep working and are never deleted, but nothing new
lands here.

Verified rather than assumed: the notice prints, the node still boots
behind it, and docker stop still exits 0 in 5s, so inserting a shell in
front of tini has not broken signal propagation.
