Stability + UX cycle. - saveConfig and writeQueueToDisk now use openSync+writeSync+fsyncSync+ closeSync+renameSync via writeFileAtomicSync. Survives power loss between write and rename (used to leave the renamed file empty and silently reset config / queue on next launch). - Per-item claimedFilenames map fixes the parallel-download race where one item finishing wiped sibling claims and let a third item collide on the same output path. - Renderer queue lookup by [data-id] (no more index drift), active tab persisted in localStorage, Escape closes the topmost open modal, Ctrl/Cmd+1..5 jumps tabs. See docs/IMPROVEMENT_LOG.md for the dated rationale and regression run. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
