Overview
Release 163.0.0 bumps the monorepo from 162.0.0 and publishes patch releases for two E2E-related packages.

@metamask/preinstalled-example-snap goes to 0.8.1 (changelog: re-add the hidden preinstall flag; manifest version and bundle shasum updated). @metamask/test-snaps goes to 3.5.2 (changelog: rename duplicate identifiers that were breaking tests). No runtime library changes appear in this diff—only versions, changelogs, and the preinstalled manifest checksum.
