All six github plugins and the local vim-herdr-navigation link had lost
their on-disk roots (plugins/github/ and ~/.herdr were gone), so every
manifest resolved to ENOENT and the config.toml plugin_action binds were
dead. Reinstalled each at its pinned commit; vim-herdr-navigation moves
from a hand-cloned local link to github:paulbkim-dev so herdr manages it.
