`license = "GPL-3.0-or-later"` has been in the manifest since the start, and
cargo-deny's allow-list carries it annotated "This crate's own licence" — but
no LICENSE file existed, so the declaration pointed at nothing.
Text copied from the jRay plugin's LICENSE after verifying it is byte-identical
to the FSF's canonical gpl-3.0.txt, rather than transcribed. 674 lines where a
single altered word changes the terms is not a file to write by hand.
No requirement trailer: this serves none, it completes an existing declaration.
