Route every per-frame interaction through the active model tile's screen
rectangle so a tiled VPORTS layout behaves like independent panes while
still sharing one shader widget:
- pick / draw / snap / box+lasso: cursor mapped to tile-local space; the
hover-activates-tile rule on ViewportMove keeps the active tile under
the cursor, so the picked camera matches what the user sees.
- pan: switched to Camera::pan_screen(dx, dy, viewport_height) so the
world-per-pixel rate matches the active tile's height instead of the
full canvas.
- grid: clipped via Frame::with_clip to the active tile rect; world→screen
adds the tile origin so the lines align with the panel.
- UCS icon: origin offset by the tile rect so the gizmo sits in the
active tile's bottom-left corner.
- render-mode picker (+ split buttons) and ViewCube hit-area: positioned
via active_model_tile_bounds with leading Spaces, mirroring the
floating-viewport pattern.
- ViewCube hover: driven by the CursorMoved/ViewportMove handlers into a
new Scene::viewcube_hover cell, so the highlight survives the cube
hit-area overlay masking events from shader::Program::update.

ViewCube tıklaması artık sabit (yaw, pitch) tablosu yerine bir yön
vektörüne (eye direction) snap ediyor. Up vektörü şöyle seçiliyor:
1. Mevcut up alın.
2. ±X / ±Y / ±Z arasından (yeni gaze ile (anti-)paralel olmayanlar)
mevcut up'a en yüksek dot-product veren cardinal axis'i seç.
3. Bu axis'i yeni gaze yönüne dik plane'e projekte et ve up olarak
kullan.
Sonuç:
- Küçük tilt'ler ilgili canonical axis'e snap olarak temizleniyor.
- TOP yukarıda iken TOP-LEFT edge tıklayınca TOP yukarıda kalıyor;
cube edge'e dönüyor ama kullanıcının "yukarı" hissi korunuyor.
- Upside-down orbit edilmişse -Z up olarak seçilir, snap baş aşağı
yapılandırmayı bozmuyor.
CubeRegion::snap_angles ve Camera::snap_to_angles yerini
snap_direction / snap_to_direction aldı.
snap_active_viewport_to_direction viewport'un view_direction'ını
günceller, twist_angle'a dokunmaz.

Remove unused `screen_delta_to_world` camera method (superseded by the
corrected pan_active_viewport formula).
Fix `is_content_viewport`: the old geometry fallback required the viewport
center to be near the origin, but DWG files never write the viewport id
field (stays 0) and the sheet viewport center is the paper centre
(e.g. 105, 148.5 mm for A4) — not the origin. This caused the sheet
viewport to be classified as a content viewport in DWG files, making it
both tessellated (border visible) and enterable via double-click.
The new heuristic uses only the scale: a sheet viewport has scale ≈ 1:1
(view_height ≈ paper height); true content viewports have deliberate
drawing scales (1:50, 1:100, …) that are far from 1.0.

- Add `active_ucs: Option<Ucs>` per-tab state to DocumentTab
- Add `ucs_to_wcs`, `wcs_to_ucs`, `ucs_z_axis`, `ucs_rotated_z` helpers
- Add `Camera::pick_on_plane` for ray–plane intersection against any plane
- Mouse picks project onto the active UCS XY plane instead of world XY
- Typed coordinates are converted from UCS space to WCS before dispatch
- UCS command now really activates/deactivates a UCS:
- `UCS W` resets to WCS (clears active_ucs)
- `UCS <name>` activates a named UCS
- `UCS SAVE <name>` saves the current active UCS
- `UCS ORIGIN x,y,z` shifts origin (in current UCS space)
- `UCS X/Y/Z <angle>` rotates the UCS around its own axes

- Add active_viewport: Option<Handle> field to Scene
- Add EnterViewport(Handle) and ExitViewport messages
- Double-click on a user viewport (id > 1) enters MSPACE;
double-click on empty area while in MSPACE exits to PSPACE
- MSPACE middle-drag pans the viewport's model-space view (view_target)
- MSPACE scroll zooms the viewport's view_height / custom_scale
- Drawing commands inside MSPACE receive model-space coordinates
via paper_to_model() coordinate transform
- Active viewport rendered with yellow dashed border (vs. cyan solid)
- Camera screen_delta_to_world helper for MSPACE pan conversion
- LayoutSwitch clears active_viewport
