Subject: [PATCH] Centralize CI on SciML reusable workflows

Convert inline CI jobs to the centralized SciML/.github reusable
workflows (pinned @v1, secrets: inherit on every caller):

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

Tests.yml and Documentation.yml were already central callers.
GPU.yml (self-hosted) and TagBot.yml left unchanged.

dependabot.yml: drop crate-ci/typos ignore; point julia ecosystem
at the dirs that actually have a Project.toml (/, /docs, /test/GPU).
