claude-code: act on the review of the nox-mesh plugin

Refuse paths with empty, dot or parent segments and a file that is also a
directory; take an item only when its key says what it is; write the view
under its lock; expand nodes all and check node names; merge the plugin's
entries into the operator's own; render every file past one that fails;
in the home, never take over the person's file, never write through a
symbolic link, keep a deleted file deleted, keep the kind's directory; and
refuse settings that would deny the console or the marketplace.
