Ortho and the running object-snap set were app-global (settings.txt only) and
Isolate/Hide was a session-only view state, so none survived save/reopen and
none were per-drawing. Bind all three to the file like AutoCAD:
- Ortho -> header.ortho_mode ($ORTHOMODE); running OSNAP <-> header
.object_snap_mode ($OSMODE bitmask) via a new SnapType<->bit map in settings
(osmode_from_snaps / snaps_from_osmode, round-trip tested). The header is the
per-drawing store, live state mirrors the active drawing: adopt header->live
on open and tab-switch, stamp live->header on save and when leaving a tab, a
fresh drawing inherits the current values, and SETVAR ORTHOMODE/OSMODE now
also update the live state. settings.txt stays as the boot/new-drawing
default; the per-file header overrides it on open.
- Isolate/Hide now set each entity's persisted invisible flag (DXF code 60,
which acadrust round-trips in DXF and DWG) in addition to the session set;
End Isolation clears it. The set is reseeded from invisible entities on load
and after undo/redo, the commands are undoable and mark the tab dirty. The
renderer already skipped invisible entities, so no render change was needed.

Phase 4.1. Handle / u64 keys dominate the hot maps (block_defn,
hatch / image / mesh caches, draw-depth map, viewport wire caches);
the default SipHash is wasted work on integer keys. Alias the std
types to rustc_hash::FxHashMap / FxHashSet crate-wide so every map and
set — including the cross-module draw-depth map shared between scene
and the GPU pipelines — uses the faster hasher consistently.
Mechanical: no behavioural change. Constructors moved from ::new() to
::default() (Fx variants carry no RandomState). Build + 13 tests green.

`model_wires_for_viewport` was tessellating with `self.bg_color` (the
model bg), so model content rendered inside a paper-layout viewport
adapted to a dark bg even though the transparent shader now reveals
the PaperCanvas sheet behind it — white wires stayed white on a light
sheet. Pass the paper bg in a paper layout.
Wire cache also needed an explicit invalidation when the bg or the
active layout changes; otherwise the cached, already-adapted wires
were returned against the new bg unchanged.
- BACKGROUND command bumps `geometry_epoch` after both branches
- new `Scene::set_current_layout` setter bumps on actual change; layout
switch + history restore use it

Add VP freeze/thaw toggle columns to the layer panel when in a paper
space layout. Each viewport gets its own column (VP 1, VP 2, …) showing
a freeze icon per layer. Clicking toggles frozen_layers on the Viewport
entity and syncs back to the panel.
- scene: viewport_list() → [(handle, label, frozen_handles)]
- LayerPanel: VpCol + vp_frozen per layer, sync_with_viewports()
- Message::LayerToggleVpFreeze(layer_idx, vp_col_idx)
- Sync VP columns on layout switch, VPLAYER cmd, undo/redo, layer ops
