pub fn discover_plugins(plugin_dir: &Path) -> Vec<DiscoveredPlugin>Expand description
Discover plugins from plugin_dir (~/.lowfat/plugins/ by default) merged
with the embedded set baked into the binary. Disk plugins win on name
collision — a user-installed git-compact shadows the bundled one.
Directory structure for disk plugins: plugin_dir/category/plugin-name/lowfat.toml (or init.toml)
