feat v1.21.0: merge and split rooms

Browse Source 
- Merge: click a room, then a neighbour. Adjacency is decided by the RESULT, not a
  heuristic: mergeRooms unions the outlines and accepts only when they collapse into one
  hole-free outline (corner touch / apart / hole => refused). A dialog picks the surviving
  name+area; the kept room keeps its id so its label and devices stay put.
- Split: click the room, then two wall points; the chord cuts it, live ruler on the cut.
  The bigger part stays the room (name/area/devices), the smaller opens the new-room
  dialog. The cut is applied only on confirm — Cancel leaves the room whole.
- Boolean geometry via polyclip-ts (proper ESM + native types; polygon-clipping ships
  named types but a default-only ESM build, breaking either tsc or the runtime).
  Verified on the real plan, where neighbouring walls overlap collinearly rather than
  match exactly — the case a hand-rolled union gets wrong. Bundle 151->202 KB.
+5 tests (72). Verified live: merge of Сауна+с/у -> 4-vertex outline, non-adjacent
refused, split preserves area (26667 -> 13333+13333), cancel leaves the room whole.

- [ ] Rooms never overlap (v1.20.0): a click strictly inside an existing room is refused with a
toast; a click ON a shared wall (including mid-span of a longer neighbour wall) still works
- [ ] Closing an outline drawn AROUND an existing room is refused; the outline stays open
- [ ] Merge (v1.21.0): two rooms sharing a wall merge into one; the dialog picks the surviving
name/area; rooms touching only at a corner or apart are refused with a toast
- [ ] Split (v1.21.0): click a room, then two points on its walls — the bigger part keeps the
name/area/devices, the smaller opens the new-room dialog; Cancel leaves the room whole
- [ ] Split: a cut with an end off the wall, or along a wall, is refused with a toast
- [ ] Esc / Ctrl+Z removes the last dot (and its line); Reset clears the path
- [ ] Closing the contour (click the first dot, ≥4 points) opens the room dialog
- [ ] Room dialog: area list shows only unassigned areas; picking an area prefills the name
