Subject: [PATCH] chore(js): upgrade vitest and coverage-v8 to 5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Combines Dependabot's #82 (vitest) and #84 (@vitest/coverage-v8): the two
must move together. Also excludes generated wasm-bindgen output and .d.ts
files from coverage — vitest 5's coverage tries to parse them and logs a
RolldownError on ambient declarations (`export const memory: ...;`).
