- Configure package.json with workspace and catalog dependencies
- Add standard tsdown.config.ts following plugin conventions
- Add vitest.config.ts for test configuration
- Update root tsconfig.json references
- Add cookie, koa-onerror, mustache, stack-trace to pnpm catalog
- Add type definitions for mustache and stack-trace
- Fix HTML syntax error in mustache template
- Remove incorrectly created packages/egg/plugins/onerror directory
