Subject: [PATCH] ci: route CI through SciML/.github reusable workflows (@v1)

Centralize this monorepo's GitHub Actions onto the shared SciML/.github
reusable workflows, preserving the existing config and coverage.

- CI.yml (Tests): drop the manual project matrix that listed `.` plus each
  lib/* sublibrary; now a clean main-package caller of tests.yml@v1 over the
  existing version matrix ["1","lts"]. Per-sublibrary testing moves to
  SublibraryCI.yml below.
- SublibraryCI.yml (new): consolidates the per-sublibrary entries into a
  single caller of sublibrary-tests.yml@v1, which auto-discovers lib/*.
- FormatCheck.yml: bespoke fredrikekre/runic-action -> runic.yml@v1.
- SpellCheck.yml: bespoke crate-ci/typos -> spellcheck.yml@v1.

Left bespoke/untouched: Downgrade.yml (already uses downgrade.yml@v1),
TagBot.yml (non-CI automation, no reusable).
