Jun-te Kim 8e487a9bae docs(elmhurst): validate slice-5 wall fix against accredited Elmhurst worksheet (uprn 200004296092)
Built the cert in accredited Elmhurst RdSAP10-Online on the lodged register
inputs; downloaded Input Summary + SAP Worksheets (committed alongside).

Confirmed:
- Slice 5 DIRECTION validated: the externally-insulated solid-brick wall is
  billed insulated by both tools (Elmhurst U 0.48, engine U 0.29), far below
  the uninsulated 1.40 the pre-fix §5.8 gate produced.
- ROOF matches EXACTLY (U 0.30, 9.35 W/K).
- Engine 71.74 = lodged 71; Elmhurst current SAP 66 (its "unknown external
  insulation" default is more conservative + this build used a generic combi
  and no keyed wall thickness, so 66 is not a clean engine-comparison).

Follow-up lead (documented in ELMHURST_FINDINGS.md): the engine feeds the
UNMEASURED lodged wall_thickness (360 mm, measured=N) into the §5.6 formula,
whereas RdSAP §5.3 uses measured thickness / Table-3 default otherwise. The
party-wall "difference" is NOT a bug (engine 0.25 is spec-correct, Table 15
row 4). Also adds the build script scripts/hyde/build_200004296092.py.

No engine change in this commit.

"""Elmhurst build for UPRN 200004296092 (RdSAP-Schema-21.0.1, END-TERRACE HOUSE,
2-storey, band B, SOLID BRICK 360 mm WITH EXTERNAL INSULATION (thickness lodged
"NI" = unknown), pitched 150 mm loft, solid uninsulated ground floor, mains-gas
COMBI (PCDB 16137 Ideal Logic combi 30 ~ generic Post-98 condensing combi),
control 2106 (CBE), double glazed ~4.31 m², 2 doors, TFA ~62, party wall 6.79 m.
Engine 71.74 = lodged 71 AFTER the §5.4 "assume 100 mm if unknown" wall fix
(slice 5); this build validates that against the accredited Elmhurst worksheet.
The KEY page is `walls`: it prints Elmhurst's insulation dropdown so we can see
how the accredited tool handles External insulation of unknown thickness. Run:
