Adds LICENSE with the MIT licence sneak chose for routewatch, copied byte for byte from sneak/webhooker's LICENSE: copyright 2026, Jeffrey Paul. The rest of the issue, .editorconfig and the Gitea check workflow, was already on next, and the README already points at LICENSE.
Judgement call: our repos write the copyright holder in several different ways and sneak named no form; webhooker's gives his full name and email address, the most explicit of them.
Model: opus-5-5
