* CI: run the gate through craft-common-actions' shared gate.yml; FreeBSD nightly and on release
ci.yml calls the shared workflow (cached apt packages, nextest, main-only cache saves, Cargo.lock check). FreeBSD runs nightly and on pushes to release instead of on pull requests. Depends on storytold/craft-common-actions#69.
* CI: build the shared gate without craft-fonts, as before
* CI: build the shared gate with release.yml's craft-fonts pin
* Packaging: pin the Windows signing client and check its hash
* Packaging: pin appimagetool and check its hash
* Reject AppImage download for architectures without a pinned appimagetool
* Pin the AppImage runtime
* Dev profile: line tables for workspace crates, no debug info for dependencies
* Tests: one integration-test binary per crate with several test files
* xtask ci: nextest, doctests, tests without examples, --keep-going; add xtask test
