The catalog plugin declares hindsight-client in its own plugin.yaml and the
plugin installer resolves it (into HERMES_LAZY_INSTALL_TARGET on the sealed
Docker image), so the pyproject extra, its exclude-newer entry and every
consumer that pre-installed it — the Dockerfile, the nix full package /
module examples / check override, and the CI `uv sync` matrices — stop naming
it. uv.lock regenerated with `uv lock` (only the hindsight-client package and
the extra leave the lock; the exclude-newer block is re-sorted by uv).
