Pull request overview

Updates the repo to use a compliant npm registry feed and aligns TypeScript/ESLint tooling across packages to work with newer Node/TypeScript settings.

Changes:

• Point npm installs at an Azure Artifacts registry via .npmrc and document auth setup.
• Update TypeScript compiler settings (Node16 module resolution, ES2020 target) and standardize rootDir in package tsconfigs.
• Refresh dependency/tooling versions (notably ESLint 10, TypeScript 5.x, adm-zip 0.6) and simplify some ESLint configs.
