Function install_lv2_plugin_lib 

pub fn install_lv2_plugin_lib(cx: &mut Cx) -> Result<()>

Installs the plugin-lv2 surface pack into cx, idempotently.

Registers one adapter card per export symbol so the LV2 host and export adapters are discoverable from the runtime. Repeated calls are a no-op.

Errors

Returns an error when registration into the context fails.
