chore: add configs private package

[shabaraba]

Why

Configuration files for ESLint, TypeScript, Renovate, license-manager, and commitlint were scattered across the js-sdk monorepo, leading to duplicated settings in each project.

Centralizing these configurations provides the following benefits:

• Easier to understand the impact of configuration changes
• Keeps each project's configuration files concise
• Facilitates sharing of configuration best practices across projects

What

Added a new internal shared configuration package @kintone/configs.

Note: This is an internal package for the kintone development team. It is not intended for public use, and breaking changes may occur without notice.

Included configurations

• ESLint: Common configuration based on @cybozu/eslint-config
• TypeScript: Shared tsconfig settings
• Renovate: Common dependency update settings
• license-manager: Common OSS license validation settings
• commitlint: Commit message validation settings

Updated root configuration files

• eslint.config.mjs: Now references @kintone/configs/eslint-config
• tsconfig.json: Now extends @kintone/configs/tsconfig
• renovate.json5: Now references @kintone/configs/renovate-config
• license-manager.config.js: Now references @kintone/configs/license-manager

How to test

• pnpm install
• pnpm build
• pnpm lint
• pnpm test

Checklist

• Read CONTRIBUTING.md
• Updated documentation if it is required.
• Added tests if it is required.
• Passed pnpm lint and pnpm test on the root directory.

The package.json specifies "globals": "^16.4.0", but the lockfile resolves this to version 16.5.0. While this is within the semver range, for consistency and reproducibility, consider updating the package.json to specify "^16.5.0" to match the resolved version.
