fix: correct publishConfig.types format in package.json files

[FL4TLiN3]

Summary

• Fixed publishConfig.types format across 22 package.json files
• Changed from invalid object format to proper exports condition format
• TypeScript can now correctly resolve type definitions for published packages

Problem

The types field in publishConfig was incorrectly specified as an object:

"types": {
  ".": "./dist/src/index.d.ts"
}

This format is invalid for the types field, causing TypeScript to fail to resolve type definitions in @perstack/core@0.0.33 and other published packages.

Solution

Moved type declarations into the exports field using the TypeScript 4.7+ recommended pattern:

"exports": {
  ".": {
    "types": "./dist/src/index.d.ts",
    "import": "./dist/src/index.js"
  }
}

Test plan

• pnpm build passes (28 tasks)
• pnpm typecheck passes (50 tasks)
• Verify type resolution in external project after publishing
