Add lairk, share laklok chat widgets, sign in the desktop app via ac-login master
lairk: the Laer Klokken chat as a place. Everyone who speaks there stands around a clock tower (CPU forms, hand-built camera so name tags and bubbles project exactly), wearing their handle colors and latest painting. Enter opens the laklok chat over the world; nobody walks yet. laklok-tema: lakChatOptions is now the one source for the chat widgets both laklok and lairk draw (+ after the input, presence, tema colors). disk.mjs: lairk joins laklok on the Enter/Escape exception list (worker rebuilt). Login: inside the desktop app, hi/login goes through ac-login (system browser, ~/.ac-token) like the other AC Mac apps, and the session comes back as session-aesthetic, which boot now honors without an Auth0 cache. The in-app Auth0 redirect failed with a callback URL mismatch off-origin. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
