Subject: [PATCH] Centralize CI on SciML reusable workflows

Convert remaining inline CI workflows to the centralized SciML reusable
callers (pinned @v1, secrets: "inherit"):

- FormatCheck.yml (Runic): inline fredrikekre/runic-action -> runic.yml@v1
- SpellCheck.yml: inline crate-ci/typos -> spellcheck.yml@v1
- Downgrade.yml: inline downgrade -> downgrade.yml@v1 (preserves if:false,
  julia-version 1.10, skip Pkg,TOML)

Tests.yml and Documentation.yml were already central callers; left as-is.

dependabot.yml: remove crate-ci/typos version ignore (typos now pinned by
the central spellcheck workflow); add /test/nopre to the julia ecosystem
directories (it has its own Project.toml).
