v0.4.0

Added

• Configurable session sort order. A new dtachSessions.sortBy setting and a
  toolbar picker (Set Sort Order) order the list by created (default —
  unchanged), last attached, name, or status (an attention queue:
  waiting → working → done → idle). The status order reuses the same run-state
  the row icon and activity-bar badge already show, so it can never disagree with
  the rows.

Changed

• Multiple sessions per folder from the Explorer. Right-click a folder →
  Open in Detach Session now opens a picker instead of silently reusing or
  creating: attach to any existing session in the folder's name family
  (<folder> and its <folder>-N siblings, newest-first, each showing live
  Claude status), or create a new numbered one. The prefilled folder name +
  Enter creates by default; attaching to an existing session is an explicit
  choice. BREAKING: the folder path no longer opens with zero prompts when
  no session exists yet — accepting the prefilled name is one Enter.
• Corrected the row tooltip and an internal note that claimed a socket's
  modification time moves on attach/detach. Nothing is ever written to a dtach
  socket, so mtime is pinned at creation — the tooltip now labels it "created"
  rather than "last modified".
