* feat(editor): tool-defaults seeding + drawTool capability; fence consumes it
Adds a generic, transient `useEditor.toolDefaults` slice keyed by tool, set
via `setToolDefaults(tool, params)`. A draw tool's create path merges its
entry when minting a node and clears it on deactivation, so a host app can
prime the next-drawn node's parameters — placing a saved preset of a drawn
kind, or a future "small / medium / large" dimension picker for
wall / slab / ceiling.
Marks the kind with `capabilities.drawTool` (helper `isDrawnViaTool`) so host
apps know to route placement through `setToolDefaults(type) + setTool(type)`
instead of cloning a finished instance.
Wires fence end-to-end: it declares `drawTool: true`, its create path merges
`toolDefaults.fence`, and the draft preview (bar geometry, cursor, HUD label
heights) reflects the seeded height/thickness so the ghost matches what will
be built. The tool clears its own defaults on unmount.

* fix(editor): restore dropped useEditor import in fence tool
The toolDefaults-seeding commit lost the `useEditor` import (formatter
stripped it), shipping a runtime ReferenceError when FenceTool mounts.
Re-add it.
