fix: rebuild trough, anvil, hand-pump, and signpost

[TMHSDigital]

Summary

• Rebuild four showcase props that read as primitive dumps next to barrel/bench: water-trough (solid U end-caps + water, into-the-hollow camera), anvil (London silhouette, 16-seg horn, torus hoops, lighter steel), hand-pump (two-diameter column, gooseneck, pump head, forked lever), signpost (thin-Y planks, diamond tips, collar cap).
• Budgets refit from live runs. Default 0, --skip-decimate 9, unknown flag 2 on Blender 4.5.11 / 5.1.2 / 5.2.1 (9e2066aef7ef). Two identical 5.2.1 defaults.
• Cycles 5.2.1 stills, PIL webp q=85 method=6, python scripts/build_gallery.py. Card alts are the full first teaches sentence; witnesses callouts match gallery.json.

Evidence (live run)

• water-trough: 4776 tris, 3 mats (168 metal / 60 water), AABB 1.162×0.528×0.488, collider 128, LOD2 0.2198 all three series.
• anvil: 1696 tris, 274 metal, AABB 0.746×0.410×0.682, collider 162, LOD2 0.2193 / 0.2193 / 0.2182.
• hand-pump: 1164 tris, 222 metal, AABB 0.610×0.364×1.049, collider 110, LOD2 0.2199 / 0.2199 / 0.2148.
• signpost: 504 tris, 66 metal / 24 board, AABB 1.368×0.201×1.566, collider 56, LOD2 0.2183 / 0.2183 / 0.1746 (5.2 COLLAPSE).
• Inspection only: gallery HTML alts/witnesses after regen.

Test plan

• blender-smoke 5.2 LTS and 4.5 LTS green on this head
• blender-smoke 5.1 green via needs-5.1
• Validate, drift-check, Socket
• Gallery cards show the new heroes without truncated alts
