chore: temporarily drop root prepare script

`pnpm install` re-fetches a git dependency from the whole-repo tarball
recorded in the lockfile; with a root `prepare` script present, pnpm
then tries to prepare the entire monorepo and fails
(ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED). Combined with vite-task-client
being excluded from the workspace, dropping this script lets `vite`
consume the client as a commit-pinned git dependency for evaluation.

Temporary: restore the husky `prepare` hook once the client is
published to npm. Contributors can run `pnpm exec husky` manually
in the meantime.
