/**
 * The "file changed on disk" conflict resolver.
 *
 * Shown when saveDocument detected that disk differs from what the editor
 * thought it had. The editor has already re-synced its sourceContent to the
 * fresh disk content with keepDraft: true — so the dialog's two actions map
 * onto concrete state transitions:
 *
 *   "Use disk version"   — replace the draft with disk content
 *                          (syncStateFromContent without keepDraft).
 *                          Destroys unsaved edits.
 *
 *   "Save my changes"    — close the dialog and re-run saveDocument.
 *                          computeEditBlocks will now diff against the fresh
 *                          disk content, so non-overlapping edits merge in
 *                          and overlapping edits win over disk for the
 *                          lines the user actually touched.
 *
 * The dialog is modal (dimmed backdrop, keyboard-trapped, click-outside does
 * not dismiss). Escape and the ✕ button both close it without taking either
 * action — equivalent to "I'll deal with this later"; the save button stays
 * dirty so the user can retry or keep editing.
