chore(release): sync 3.3.4 version bump back into develop

The v3.3.4 release prep landed on main but was never merged back into
develop, leaving every version-bearing file one release behind. Bumps
pyproject.toml, mempalace/version.py, both plugin manifests, the
marketplace entry, the README badge, and the lockfile to 3.3.4 to match
the tagged release.
