feat: clean render mode + scene visibility + full export overhaul

RENDER MODE (the main fix):
When rendering/exporting, setIsRenderMode(true) is called FIRST.
This hides ALL of these from the canvas:
❌ Grid
❌ Gizmo helper (axis widget)
❌ Selection rings around models
❌ TransformControls (gizmo arrows)
❌ Camera marker objects (box + lens + cone)
❌ Deselect plane
❌ OrbitControls
❌ Camera view HUD / brackets / crosshair
Only renders: models + lighting + environment + floor + background
Render mode exits automatically on cancel or completion.

useStore.js:
- isRenderMode: false (separate from isExporting so UI can check it)
- showGrid / showGizmo / showCameraObjects / showContactShadows toggles
- setIsRenderMode / setShowGrid / setShowGizmo etc.
- renderWidth / renderHeight for future offscreen rendering

Scene.jsx:
- Floor: Grid and ContactShadows check !isRenderMode && showGrid
- CameraMarkers: hidden when isRenderMode || !showCameraObjects
- EditorGizmo: hidden when isRenderMode || !showGizmo
- Deselect: hidden when isRenderMode
- OrbitControls: disabled when isRenderMode
- CamHUD overlay: hidden when isRenderMode
- RenderIndicator: red REC dot shown during render
- Playback: loop mode wired correctly

ModelManager.jsx:
- Selection ring: hidden when isRenderMode
- TransformControls: hidden when isRenderMode

ExportPanel.jsx (full rewrite):
- enterRenderMode() called before first frame capture
- 200ms grace period for React to re-render without UI
- exitRenderMode() called on completion/cancel
- PNG sequence export mode (downloads each frame as JPEG)
- Video (WebM VP9 12Mbps) or PNG sequence toggle
- 24/30/60fps output presets
- Frame quality slider (50%-100%)
- Gradient progress bar (accent→accent2→accent3)
- File named with project name + timestamp
- Live frame counter in status
- Cancel properly exits render mode

Toolbar.jsx:
- ⊞ Toggle grid button
- ⊕ Toggle gizmo button
- 🎥 Toggle camera objects button
