YATM third-party notices

cmd/lto-info includes source adapted from speed47/lto-info:
https://github.com/speed47/lto-info
Its MIT license is reproduced in licenses/lto-info.LICENSE.

internal/media/readplan/perturb.go adapts weak-edge sampling and
candidate-walk structure and constants from JPT/LKH-AMZ's KSwapKick.c:
https://github.com/heldstephan/jpt-amz/blob/dc4ebc0aa091d4d1eb7dc7d9b9b2d8f8c19664ce/LKH-AMZ/SRC/KSwapKick.c
The source-directory MIT license, Copyright (c) 2021 Keld Helsgaun, is
reproduced in licenses/jpt-lkh-amz.LICENSE from the same revision's
LKH-AMZ/SRC/LICENSE.txt.

The @react-dnd/* packages inherit the react-dnd monorepo's MIT license:
https://github.com/react-dnd/react-dnd/blob/main/LICENSE
Some published subpackages omit that file. A copy is maintained in
licenses/react-dnd.LICENSE and included with their distribution notices.

Release archives also contain licenses/dependencies.json and per-dependency
license/notice files collected from the actual Go and production frontend
dependencies. YATM's own license does not replace those upstream terms.
