pipeline cards, context menus, presets, settings overhaul

rewrote pipeline as draggable card strip with per-rule config popovers,
added right-click menus to pipeline cards, sidebar tree, and file list,
preset import/export with BRU format support, new rules (hash, swap,
truncate, sanitize, padding, randomize, text editor, folder name,
transliterate), settings dialog with all sections, overlay collision
containment, tooltips on icon buttons, empty pipeline default
