fix: point eslint package entries to preset

[Pugsin]

Summary

• point @storm-software/eslint package-level main and types at the published preset entry files
• leave the existing exports map unchanged

Why

The published package root export already resolves to dist/preset.js / dist/preset.d.ts, but the package-level main and types fields point to dist/index.js / dist/index.d.ts. Those dist/index.* files are not present in the npm tarball, so tooling that reads the legacy package fields can resolve to missing files.

Validation

• npm view @storm-software/eslint@0.170.90 main types exports --json
• npm pack @storm-software/eslint@0.170.90 --dry-run --json confirms dist/preset.js and dist/preset.d.ts are published, while dist/index.js is not
• node -e "const p=require('./packages/eslint/package.json'); if(p.main!=='./dist/preset.js'||p.types!=='./dist/preset.d.ts') process.exit(1)"
• git diff --check

Note: I could not run full pnpm workspace gates here because pnpm is not installed in this environment. This is a package metadata-only fix.
