ci: fix eslint parser devDeps, typed linting config, prettier formatting

- Add @typescript-eslint/parser and @typescript-eslint/eslint-plugin as
  direct devDependencies (were only transitive, not linked in node_modules)
- Add files pattern and parserOptions.project to eslint.config.mjs so
  ESLint finds and type-checks src/**/*.ts files correctly
- Run prettier --write to fix formatting across all src files
