TaskDetailView now edits Model / SystemPrompt / Agent inline (LostFocus
save), matching the modal editor. Both TaskEditorView and TaskDetailView
gain a Browse button that opens a .md file picker — external agent
paths are preserved on reload via a synthetic AgentInfo entry. Both
views also render the per-task subtask checklist (CheckBox + TextBox +
remove), with diff-on-save in the editor and inline-save in the detail
panel.
