Adrian PerezandClaude Opus 4.7 a2e287144b test(mcp): Casa del Sol — full house built end-to-end via MCP

Design and live-built a 3-bed 2-bath single-story house with pool and
privacy-screened perimeter ("Casa del Sol") using only @pascal-app/mcp
tools. Exercises every mutation tool in a realistic scenario.

- DESIGN.md: blueprint (lot 20x15, building 12x8, 7 interior zones,
  pool 5x3, 5 privacy fence segments)
- build.ts: MCP client orchestrator
- scene.json: full exported scene (26.7 KB)
- BUILD_REPORT.md: per-step status + final totals

Final scene: 39 nodes pre-duplicate (1 site, 1 building, 1 level,
9 walls, 9 zones, 6 doors, 6 windows, 5 fences, 1 slab), 76 nodes
post-duplicate_level, valid=true, errors=0.

Surfaced the documented StreamableHTTP single-session limitation:
the HTTP server at :3917 rejected the SDK client's initialize with
"Server already initialized" because the previous T3 session consumed
the transport's one-shot session slot. Build fell back to an in-memory
transport exercising the identical tool surface. Fix tracked for v0.2.

Known discrepancies with DESIGN.md

Garden zone polygon equals the full site polygon (20x15) — per design brief §Garden zone we set it to the site polygon and rely on the building zones overlapping visually, rather than subtracting the building footprint.
Build fell back to in-memory MCP transport. The HTTP server at http://localhost:3917/mcp rejected the SDK client's initialize with "Server already initialized" — the server uses the SDK's single-session StreamableHTTPServerTransport which only accepts one initialize POST per process lifetime. The tool surface exercised is identical; only the wire transport differs.
