0.12.0: document drawer redesign, PWA install, clip/audio context menus + push-cascade

- Document drawer slides out from under the topbar (no tab, no hover peek); opens via project-name button, closes on outside-click or ESC. Layout: inputs row + divider + preset row, presets user-managed via popup and persisted in localStorage. - PWA manifest + minimal service worker so Chrome installs RUWIO as a standalone app — suppresses the native fullscreen exit overlay. - Clips and audio clips get right-click context menus (Duplicate / Delete) via new `duplicateClipInstance` / `duplicateAudioClip` store actions. - Clip moves cascade non-overlap in both directions; `setAudioClipPosition` now pushes backward as well as forward. New `setClipInstancePosition` gives clip instances the same behaviour. - Library drags carry timeline-shaped ghost previews (audio pill, clip pill, button thumb) instead of the library row; clip lane renders a dashed drop-target ghost and rejects window-overlap drops. - Scene / Clipart drawer tabs disappear in fullscreen; the 24 px they occupied is reclaimed for the stage. Play button sits on the exact horizontal center via a 3-column grid in the transport cluster. - Tests: context menu + push-cascade + duplicate action coverage for both clip kinds; DocumentDrawer suite rewritten for the slide-out model.
