TSLint was deprecated and archived in 2019. Replaces it with: - eslint@^8.57.0 (v8 required by @typescript-eslint@7 peer dep) - @typescript-eslint/eslint-plugin@^7.0.0 - @typescript-eslint/parser@^7.0.0 Uses legacy .eslintrc.js format for eslint@8 compatibility. Disables rules that fire on existing code to keep zero errors on first pass. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Zero errors on the existing codebase. 136 pre-existing unused-var issues surface as warnings (not errors) so the build doesn't break. These can be cleaned up separately.
