Generify the snapping/modifier HUD off the FSM scope and node declarations
instead of wall-creation-shaped, leaking pills.
- Per-context snapping (`snappingModeByContext`, persisted): wall / item /
polygon mode-sets with exclusive modes (grid | lines | angles | off), each
doing exactly what its chip says. Context is node-declared via the new
`NodeDefinition.snapProfile` ('item' | 'structural'); the resolver maps
(profile × action) → context with no per-kind switch.
- Scope-driven HUD: helper-manager reads the interaction scope; reshaping
(endpoint/curve/boundary) and item move get their own chip, no select-hint
leak. Rotate R/T rounds to 45°; Alt = force-place only (hidden for
structural kinds); Shift = cycle everywhere.
- Slab/ceiling drafting: Shift=cycle, mode-aware grid/angle, Enter finishes
(minDraftVertices); polygon boundary vertex/edge drag begins a reshaping
scope. Fix grid/angle being ignored on boundary edit + slab creation:
make resolveSurfacePlanPointSnap exclusive (alignment gated on magnetic) so
grid/angles keep the snapped fallback instead of the raw cursor.
- Painter application scope: node-derived (single/object/matching/room) from
the hovered node, cyclable via Shift, single-source HUD chip.
- Remove the redundant GridSnapControl from view-toggles (grid step lives in
the contextual HUD now).

The 7th and last of the legacy interaction flags. The node being placed/moved
now lives inside the interaction scope's `placing`/`moving` variant (carried
inline, since fresh-placement/duplicate drafts aren't in the scene yet), read via
`useMovingNode()` / `getMovingNode()` / `movingNodeOf(scope)`.
- scope.ts: `placing`/`moving` carry `node: AnyNode`; add `movingNodeOf`.
- use-interaction-scope.ts: `useMovingNode` (hook) + `getMovingNode` (imperative);
no useRef snapshot needed — the node is set once at `begin`, stable for the gesture.
- use-editor.tsx: drop the `movingNode` field + the `set({ movingNode })` writes.
`setMovingNode` still drives the scope and still sets `movingNodeOrigin` /
`placementDragMode`, so cross-store subscribers keep firing. Param + ~90 call
sites unchanged.
- migrate ~17 reader sites to `useMovingNode()` / `getMovingNode()`; drop
`movingNode` from lib/scene.ts; export `movingNodeOf`.
Every interaction flag is now derived from the single authoritative scope; only
`movingNodeOrigin` + `placementDragMode` intentionally remain as useEditor flags
(they outlive the scope / gate companion behavior).

Migrate `curvingWall`, `curvingFence`, `movingWallEndpoint`, `movingFenceEndpoint`
(and their setters) off `useEditor` onto the authoritative interaction scope.
The `reshaping` scope variant gains an `endpoint` discriminator; existence
checks read `useIsCurveReshape()` / `useEndpointReshape()`, and the few sites
that need the node (affordance-tool mounts, wall-vs-fence type checks) read it
from `useReshapingNode()` — a frozen drag-start snapshot, mirroring the old
flags so the tools' own per-frame writes don't feed back. `MovingWallEndpoint`
/ `MovingFenceEndpoint` move to the kind-owned tools that consume them.
`editor-api` is simpler: endpoint engagement is kind-agnostic, and the
`engageMove` reshape clears are gone (the scope is single-owner).

Migrate the two pure-mirror interaction flags off `useEditor` onto the
authoritative `useInteractionScope`. Both carried payloads byte-identical to
the scope union, so this is a zero-behaviour-change refactor: readers use the
reference-stable `useEditingHole()` / `useActiveHandleDrag()` hooks (or the
`getEditingHole()` imperative read), and producers drive the scope directly
with guarded `endIf` so clearing one interaction never stomps an unrelated
scope. Adds the `holeEditScope` builder + a no-leaked-flag invariant test.
Closes the first slice of the legacy-flag deletion; the rich-payload flags
(movingNode, curving*, *Endpoint, placementDragMode) remain.

Implements plans/editor-placement-interaction-overhaul.md: an authoritative
interaction-scope state machine plus the catalogued placement/interaction
fixes, and split-view floor-plan performance.
- Interaction-scope spine (lib/interaction/* + store/use-interaction-scope),
driven from central useEditor setters; overlay scoping (zone labels,
context badges, floating action menu) reads resolveOverlayPolicy.
- Bug tracks A/B/D/E/F/G/H: handle/cutout raycast, footprint validity,
auto-slab loop, ceiling hosting, B-key tool desync, 2D drop offset,
per-frame jank.
- Snapping modes (grid/lines/angles/off) + contextual HUD chips; modifier
model (Shift=cycle, Alt=free place, Ctrl=grid step).
- Item move now tracks the cursor 1:1 (was a laggy per-frame lerp); handle
rig hides during a whole-node move; rotate gizmo advertises Shift=free
rotation in the HUD and hides the move cross while rotating.
- Floor-plan perf: pause live reactivity while in 3D-only view; per-node
geometry cache so only changed nodes rebuild on a drag; hoist wall miters
to a once-per-pass ctx.levelData (O(N^2) -> O(N) on wall/opening drags).
