Paper-space commands could not pick model geometry displayed by a layout
viewport: `hit_test_wires` deliberately excludes viewport content in PSPACE,
and that has to stay true for selection. This adds the capability as a separate
query rather than by changing those semantics.
`OpenCADStudio::paper_viewport_snap` walks the current layout's displayed
content viewports top-most first, skips those whose display is off or whose
clip boundary excludes the cursor, and for each one runs the EXISTING snap
engine against that viewport's model wires using the viewport's own camera and
screen rectangle (`viewport_edit_frame_for`). The accepted model point is
mapped back onto the sheet with `ViewportFrame::model_to_paper`, so everything
downstream keeps working in paper coordinates — LINE still draws at the
projected paper point. Grid snap and the paper-space rubber-band origin are
suppressed for that pass; results outside the clip are rejected so no snap
lands on a clip cut. Locked viewports snap like unlocked ones.
No projected geometry is rebuilt per pointer event: the wire set is the
renderer's resident per-viewport Arc (`model_wires_for_viewport_arc`) and the
broad phase reuses the shared interaction index over it.
The result is merged with the ordinary paper-sheet snap by `snap::merge_snap`,
which applies the engine's own priority-then-distance rule, in both the
cursor-move and the click paths.
`SnapResult` gains Copy fields `viewport: Option<Handle>` and
`source: Option<DimensionAssociationSource>`; the engine fills `source` from
the owning wire wherever it knows it. `AcceptedSnap::from_snap` converts a
result plus frame into the shared PR2/PR3 contract type.

`Scene::viewport_frame` derives the paper<->model mapping (paper_center,
model_target, paper-per-model scale, in-plane twist, lock state) from
`camera_for_viewport` — the same camera the renderer displays the viewport's
contents with — so a snap computed through the frame lands on the pixels the
GPU drew. Oblique / mirrored / perspective viewports return None.
Also generalises the MSPACE editing adapter: `viewport_edit_frame_for(handle)`
returns the camera + screen rect for any viewport, and `viewport_edit_frame`
becomes a wrapper over it for the active one. Adds
`viewport_displays_paper_point` (rectangular bounds plus a non-rectangular clip
boundary polygon, tested in paper coordinates) and public accessors for the
layout's content viewports and their VP ON state.

PropValue::ParamRow/ParamAddRow, the PropParamInput/Commit/Delete/AddNew
messages, their command_driver handlers (on_prop_param_commit/_delete/
_add_new, resolve_named_parameter_edit), and their render functions all
already existed — but nothing ever constructed the "Parameters" section
that would route data to them, so the whole inline add/rename/redefine/
delete workflow was unreachable from the UI. Adds that missing section
to the no-selection page in refresh_properties, alongside a new
PropValue::ParamsVisibilityToggle header row (mirrors the existing
show_constraint_values setting) for toggling whether constraint pills
show their driven value/parameter name.
Users can now manage named parameters inline in the Properties panel
(live resolved values, add/rename/redefine/delete) as an alternative to
the separate PARAMETERS modal, which continues to work unchanged.

Six one-shot alignment commands for the current selection —
ALIGNLEFT/ALIGNHCENTER/ALIGNRIGHT/ALIGNTOP/ALIGNVCENTER/ALIGNBOTTOM —
distinct from the existing point-picking ALIGN/ALIGN3D command: each
nudges every selected object (or complete group, via new
Scene::selected_object_units) so its bounding-box edge/center lines up
with the extreme edge/center already present in the selection, closer
to a word processor's "align objects" than AutoCAD's 3-point ALIGN.
Wired as plain one-click Tool entries in the Modify extension panel,
next to the existing ALIGN entry, matching that panel's flat-list
convention (no point prompts, so no dropdown submenu needed).

Constraint delete: a Properties-panel row delete button, viewport
click-to-select on a constraint glyph pill with Delete-key support, and a
right-click "Delete Constraint" menu item — all routed through one
undoable Scene::selected_constraint-aware path.
Fixes two named-parameter bugs found while testing that feature:
- DIMCONSTRAINT: a parameter named like a mode-switch keyword ("r", "d",
"a", "x", "y") could never be referenced, since the keyword check ran
before the parameter-name check.
- PARAMETERS modal Apply rebuilt Scene::named_parameters but never
refreshed the Properties panel, leaving renamed/deleted rows stale
until an unrelated refresh (e.g. a selection change) happened to occur.

Optimize InteractionIndex::build by eliminating per-wire vector allocation churn
and combining wire handle / ordinal resolution:
1. Introduced WireIndexBatch to chunk wires into batches of 256 wires. Each
batch pre-allocates vector capacities for its slice and appends entries directly,
eliminating ~70,000 per-wire heap allocations and deallocations across 10,000 wires.
2. Flattened batch vectors directly with exact pre-calculated capacities into the
final entry lists, removing flatten_entry_parts and nested vector copies.
3. Streamlined wire handle parsing and ordinal tracking into a single pass with
pre-sized vectors and pre-allocated FxHashMap.
Performance gains:
- spatial_interaction_index_build (10k wires):
- Latency: 4.88 ms -> 4.01 ms (-17.8%)
- Mean latency: 4.93 ms -> 4.05 ms (-17.8%)
- Throughput: 2.05M wires/s -> 2.53M wires/s (+23.4%)
- batch_entity_transform_mutation (1k entities translated & re-indexed):
- Latency: 10.92 ms -> 8.95 ms (-18.0%)
- Mean latency: 11.28 ms -> 9.52 ms (-15.6%)
- Throughput: 92.4k entities/s -> 111.3k entities/s (+20.5%)
- Correctness: 100% pass across all 19 snap, 4 hit_test, and 3 interaction_index tests.
Entities that carry the standard PE_URL XDATA record (what HYPERLINK writes)
can now be followed from the canvas: Ctrl+click opens the link in the system
browser and consumes the click, so no box/lasso selection starts.
- scene::selection::pe_url_of() reads the record with the same rule as the
Properties panel hyperlink field; unit-tested.
- The ViewCube/compass hit region wins over a hyperlink drawn beneath it.
- Unchanged behaviour when Ctrl is not held or the entity has no link.
