CI runners configure pnpm with --store-dir=.pnpm-store (project-local
CAS) for cross-run caching. Prettier and ESLint were scanning into it
and finding 333 unformatted JSON files.
Added to .prettierignore and eslint.config.js globalIgnores:
- .pnpm-store / .pnpm — pnpm content-addressable store variants
- coverage — future test runs (Vitest in Phase 3)
- .cache — generic build cache directory
Local Windows trees aren't affected (pnpm uses the global store at
~/.local/share/pnpm/store) but the rules cover both paths.
