feat: add skip_confirm_for_delete option (#77)

feat: add \`skip_confirm_for_delete\` option

Problem: there was no way to suppress the confirmation popup when the
only pending operations are deletes. \`skip_confirm_for_simple_edits\`
explicitly excludes deletes, so users who delete frequently had no opt-out.

Solution: add \`skip_confirm_for_delete = false\` config option. When true,
\`confirmation.show()\` skips the popup if every pending action is a delete.
