Docs request for a multiarch snaps guide (one snap per arch, cross-building, CI setup, supported platforms). Reporter acknowledged partial resolution in Oct 2024; platform docs since rewritten and reorganized in the repo.

Suggested action: close stale

Reason: The reporter stated in Oct 2024 that the questions were 'addressed, at least partially' via a forum post, and a maintainer (dilyn-corner) answered each question with links to existing docs. Since then, the platform docs were rewritten (PR #6069) and reorganized (PR #5440), and a dedicated cross-compilation how-to (docs/how-to/integrations/craft-a-cross-compiled-app.rst) now exists, covering all four questions raised. No activity in ~18 months.

Issue body

### What needs to get done We should document how multiarch and snaps work: - Is there one *.snap file per arch (arm64, amd64, ...), or a single snap can be multiarch? - For testing purposes, can I cross-build a snap on my machine? E.g. build an arm64 snap on my amd64 machine? What if it's rust/go -- is it then possible to cross build? - What is the recommended way of setting up CI for multiarch builds? Does it have to involve launchpad? - What platforms are supported? For example, [nushell publishes](https://github.com/nushell/nushell/releases) for x86_64, riscv64gc, armv7, aarch64-pc, aarch64-apple. ### Why it needs to get done Help users understand multiarch snaps so they can produce more compelling snaps.
