@CharlieHelps CI is failing with ERR_PNPM_OUTDATED_LOCKFILE. please resolve the issue.

[charliecreates]

@shellscape Fixed. I updated pnpm-lock.yaml to include the dependency graph changes from packages/wasm/package.json, pushed commit 4d029fe to this PR branch, and re-ran pnpm install --frozen-lockfile locally (now passes).

@CharlieHelps why did you add types-registry to wasm? That dependency wasn't needed previously and it doesn't exist as a string reference in master

[charliecreates]

Good catch — that dependency was accidental from the Vitest migration edit. I’ve removed types-registry from packages/wasm/package.json and cleaned the corresponding lockfile entries in 9013f9f. I also re-ran pnpm --filter @rollup/plugin-wasm test and pnpm --filter @rollup/plugin-wasm test:ts; both pass without it.
