feat: column node with door/window nodes improvement

[sudhir9297]

What does this PR do?

This PR significantly upgrades the door, window, column, and floorplan rendering systems, adding flexible shaped openings, a full procedural column workflow, cleaner floorplan visuals, and architecture cleanup that moves viewer-specific geometry out of core.

It enables:

• Rectangle, rounded, and arch top shapes for windows and doors
• Rounded and arched wall cutouts with reveal radius support
• Door leaves, glass, rails, and panels that correctly follow curved shapes
• A complete procedural column node, placement workflow, renderer, and settings panel
• Cleaner separation between core schema/data and viewer geometry systems
• Improved guide/reference image handling and reference scale UI behavior
• Broader floorplan visual refinements across walls, openings, slabs, ceilings, stairs, roofs, items, and reference overlays
• Updated first-person collision behavior for doors, windows, and walkthrough logic
• Stronger material plumbing, UV mapping, icons, SVG item symbols, and viewer renderer integration

Door & Window Shapes

• Added rectangle, rounded, and arch top shape support for windows.
• Added rounded window corner controls, including individual corner radii.
• Added rectangle, rounded, and arch top shape support for doors.
• Added rounded door top-corner controls for top-left and top-right only.
• Added reveal radius support for rounded window/door wall cutouts.
• Added arched and rounded wall cutouts for windows and doors.
• Added arch/rounded shape controls in the door and window property panels.
• Added arch height controls for both regular items and opening-only mode.
• Updated door/window schemas and panels for opening, shape, and material-related controls.

Door Rendering & Geometry

• Updated door rendering so the door leaf itself follows the curved top shape when opening/closing.
• Fixed curved door glass/panel segments so they render inside rounded/arched door leaves.
• Fixed curved door segment dividers/rails to clip correctly inside the shaped door leaf.
• Rebuilt arch door frame geometry to avoid broken/extra frame artifacts.
• Switched arch curves to smoother elliptical arc geometry so the shoulders do not look sharp.
• Added shallow-arch fallback for doors so low arch values render a proper head bar instead of a thin plane.
• Fixed arch height slider commit behavior so values like 0.10 do not snap back to the default.
• Moved door and window geometry systems from core into viewer systems.

Column System

• Added a full column node schema in core, including dimensions, base/capital controls, shaft profile controls, rings, twist, bevel/softness, presets, and material fields.
• Registered columns across core/node unions, scene registry, viewer node renderer, selection managers, sidebar tree, panel manager, and structure tool UI.
• Added column placement and movement tools.
• Added the column settings panel with presets, shaft controls, base/top controls, bevel/softness, rings, twist, and proportions.
• Added column floating action support: move, delete, and duplicate.
• Added the procedural column renderer.
• Moved column geometry/UV helper generation into packages/viewer/src/systems/column/column-geometry.ts.
• Added UV mapping support for column boxes, rounded boxes, cylinders, cones, spheres, and torus-like parts.
• Added column tree node support in the site/sidebar panel.
• Added/updated column icons.

Architecture & Tooling Cleanup

• Removed the column tool's direct useViewer dependency; selection after placement is handled by ToolManager.
• Moved guide/reference-scale UI events out of core into editor-local packages/editor/src/lib/guide-events.ts.
• Moved door and window geometry systems from core into viewer systems.
• Updated viewer systems/renderers for slab, ceiling, wall, roof, stair, fence, item, spawn, door, window, guide, and column integration.
• Updated material plumbing and viewer materials support.

---

Guide & Reference Image Improvements

• Added guide/reference image improvements, including local guide image handling.
• Added replace/delete controls for guide images.
• Added guide lock and visibility UI.
• Added reference scale state.
• Improved guide/reference-scale UI event ownership by keeping editor-only behavior in the editor package.

---

Floorplan & Reference Floor Improvements

• Added floorplan/reference-floor improvements and large floorplan interaction updates.
• Added or updated floorplan visuals for stairs, roofs, items, walls, openings, slabs, ceilings, and reference guides.
• Improved floorplan rendering consistency across structural elements and item symbols.
• Updated viewer systems/renderers for floorplan-facing slab, ceiling, wall, roof, stair, fence, item, spawn, door, window, guide, and column integration.

---

First-Person & Collision

• Added/updated first-person collision world logic.
• Updated door/window behavior so shaped openings and walkthrough rules match the intended geometry.
• Improved collision integration for door, window, and opening workflows.

---

Item Symbols & Visual Assets

• Added item floor-plan SVGs for office chair and sofa.
• Added/updated column icons.
• Updated material plumbing and viewer materials support.
• Added UV mapping support for procedural viewer parts used by columns and related geometry.
