Subject: [PATCH] Migrate CI to centralized SciML reusable workflows

Normalize CI to the Sundials.jl standard set via SciML/.github reusable
workflows (pinned @v1):

- Add Tests.yml caller (version matrix ["1","lts"]); repo previously had
  no Tests workflow.
- Convert Downgrade.yml to downgrade.yml@v1 (kept disabled with if:false,
  julia-version 1.10, skip Pkg,TOML as in the original).
- Convert FormatCheck.yml (Runic) to runic.yml@v1.
- Convert SpellCheck.yml (typos) to spellcheck.yml@v1.
- dependabot.yml: drop the crate-ci/typos ignore block; preserve the
  existing github-actions and julia (/, /test) update configs.

TagBot.yml left unchanged. No docs/ dir, so no documentation workflow.
No CompatHelper workflow existed. Repo was already Runic-formatted
(verified locally) and passes typos cleanly.
