Omnibutton (mobile/omni.rs): a context FAB whose radial holds the active layer's
drawing tools laid out in a staggered inner/outer arc, plus a "+New" petal
(create Vector/Audio/MIDI/Raster/Video layer, Group, Import, and Split/Duplicate
when a clip is selected — dispatched as MenuActions) and a "more" petal that
opens a full-tools grid when the layer has extra tools. Contextual: the tool ring
only appears when the Stage is in the visible window; off-Stage the FAB is a
"+New" create button. Tools/creates use Lucide icons. Pane-internal adds
(nodes/notes/instruments) deferred to P6.
Playback fix: document.current_time (read by the renderer for animation eval and
video-frame decode) was only synced from the audio playback position inside
TimelinePane::render_content. In the mobile shell, panes render on demand, so with
the timeline off-screen current_time went stale and the Stage froze during
playback. Move the sync into the per-frame block in update() so it runs regardless
of which panes are visible.
