Replaces .eslintrc.json, .eslintrc-json.json, and .eslintignore with eslint.config.mjs flat config. Upgrades all ESLint plugins to latest versions. Removes eslint-plugin-import and its resolvers (replaced by typescript-eslint's built-in resolution). Empties dry-aged-deps exclusions as all dependencies are now current. https://claude.ai/code/session_01HNvBcQzT1SviRqkUpP5Xce

Major ESLint migration touching linting config, plugins, and npm scripts. All existing lint rules have been preserved. Source code changes are limited to minor jsdoc formatting auto-fixes.
