* feat(editor): stage overlay slot, preselectable snapshot crop, pro capture overlay
- Editor/EditorLayoutV2 gain a stageOverlay slot rendered over the canvas
but under the viewer toolbar (z-10 < z-20), so hosts can swap in a
full-stage surface (e.g. studio gallery) without unmounting the WebGL
canvas; FloatingLevelSelector hides while a stage overlay is active
- CaptureMode 'standard' accepts an optional crop preselection
(SnapshotCropMode, exported) so hosts can enter capture with
standard/viewport/area already chosen
- SnapshotCaptureOverlay restyle: letterboxed 16:9 frame with corner
accents + rule-of-thirds for standard mode, thirds grid in viewport
and area modes, top-center crop/format HUD chips, shutter button with
capture/saved states — all existing crop, drag, resize and preset
behaviors preserved

* feat(editor): standard-capture aspect presets, capture scrim, caption fix
- Standard crop gains aspect presets (16:9, 9:16, 4:3, 3:4, 1:1) — clicking
the active Standard chip opens the picker; the letterbox frame, HUD and
output resolution follow the choice
- ThumbnailGenerateEvent carries standardSize; ThumbnailGenerator
center-crops to it (default stays 1920×1080)
- Subtle bottom scrim keeps shutter/caption readable on bright scenes
- Fix missing space in the snapshot caption

* feat(editor): standard-capture aspect preselect via CaptureMode
Hosts (the studio capbar) can now pass standardAspect alongside crop when
entering capture mode; the overlay initializes its aspect picker from it.
SnapshotStandardAspect exported.
