v0.1.2

What changed

• Refresh conflict protection: clean drafts auto-sync to the latest remote data; dirty drafts are preserved with an explicit 重新载入 control and an accessible 远端已更新 live status.
• Serialized saves: reasoning saves and refreshes are queued so an older response can never overwrite a newer snapshot; save revisions are resolved at execution time.
• Save-during-edit rebasing: edits made while a save is in flight are preserved on a fresh baseline, avoiding obsolete-revision conflicts on the next save.
• Accessibility: save status and the remote-change notice are announced via role=status + aria-live=polite, with empty live regions hidden.
• v0.1.1 UI redesign carried forward: compact model cards, unified reasoning pills, DSH semantic tokens, 375px responsive layout.
