A failing debug assertion or overflow without correctly wrapping or saturating is a bug, but the `debug` profile that has these enabled does not run enough test cases to hit edge cases that may trigger these. Add a new `release-checked` profile that enables debug assertions and overflow checks. This seems to only extend per-function test time by a few seconds (or around a minute on longer extensive tests), so enable this as the default on CI. In order to ensure `no_panic` still gets checked, add a build-only step to CI.
