createToolAttribution permanently replaced the global tools service's
register method and never undid it: after the plugin was disabled,
removed, or reloaded, later registrations kept running through the dead
hook's wrapper, which retained the live map and recorded into it.
The wrap now registers a fiber effect whose disposer peels every wrapper
this incarnation installed back to the true original, so the global
instance is left exactly as it was found. A guard keeps the restore
order-independent: a closure that finds a newer incarnation's wrapper
installed does nothing, letting that incarnation's own effect own the
cleanup. ctx.effect exists in every supported dsh version (cordis 4.0.1
since 0.1.0-rc.7).
