Brandon Thomas 8a83f8c6ce LR-BEHAV-BG-TASKS: background export with progress and cancel ... - Engine: export split into prepare_export (session thread, cheap) and PreparedExport::run (Send: read/decode/render/encode); run_batch with per-photo progress, cancel and collected errors; export_batch keeps the stop-at-first-error behaviour for scripted calls. - Desktop: the Export dialog, Export with Preset (menu and context menu) and Export with Previous run their batch on a worker thread (app.export {background: true}); a progress panel shows count / file / Cancel; ui.inspect reports export {running, last}. - Headless: settle waits for a running export; `lightcraft-cli snapshot` finishes it before exiting. Web keeps foreground exports (downloads are main-thread). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>		2026-10-01 22:27:06 -04:00
