Writes up the principle behind WP-70's three tracks ("build test data
through the same door production code uses") as ADR-0006, with a decision
table for which fixture idiom fits which test type. Updates the
test-strategy skill (adds the Fixtures rule, fixes its stale pre-monorepo
src/app/... worked-example paths) and the shared Storybook testing.mdx page
to match. Closes WP-70 with the signatures/counts as actually shipped.

- fix: wire remark-gfm into addon-docs so GFM pipe tables in *.mdx render
(previously raw text in cibg-gaps/layers/atomic-design docs)
- add src/docs/i18n.mdx (Foundations/Internationalization): the $localize
locale seam + how to test languages without coupling to copy
- add src/docs/testing.mdx (Foundations/Testing strategy): per-layer spec
matrix, house style, Storybook a11y gate, GREEN gate
- add .claude/skills/test-strategy skill
