fix(hindsight): align client version to 0.6.1 across all sources

The lazy_deps pin (memory.hindsight -> hindsight-client==0.6.1) was newer
than the plugin's stated floor (>=0.4.22). Align _MIN_CLIENT_VERSION,
the setup wizard dep string, plugin.yaml, and the README to 0.6.1 so the
floor check, auto-upgrade target, and runtime lazy-install all agree.
Also drops the redundant local _MIN_CLIENT_VERSION redefinition in
post_setup.
