Subject: [PATCH] Centralize CI on SciML reusable workflows

Convert all CI workflows to the centralized SciML/.github reusable
callers (pinned @v1, each with secrets: inherit):

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

Tests.yml already used tests.yml@v1; left unchanged (already has secrets: inherit).

Delete CompatHelper.yml. Remove the crate-ci/typos ignore from dependabot.yml.
