Replace AVA + @ava/typescript + c8 with Vitest + @vitest/coverage-v8. - Run TypeScript tests directly, no compile-to-lib step needed - vitest.config.ts carries over AVA behavior: RUNNER_TEMP env, 120s timeout, serial file execution - Convert test.macro to a plain async helper; t.is/t.regex to expect - Rename test/functions.ts -> test/functions.test.ts - Coverage still lands at coverage/lcov.info for Codecov - Drop eslint-plugin-ava and its config block
