chore(meta): wiki sweep — 2,131 dead heightmap links, nav refresh, GOVERNANCE reality (T-1070, T-1071)

- T-1070: scaffold_bodies.py heightmap link now conditional (bake criteria
  per import_heightmaps.py); surgical removal of the dead image line from
  all 2,131 body pages lacking the file (267 with the file keep theirs)
- T-1071: 26 real link breaks fixed (knowledge/→concepts/, pre-governance
  decision anchors, 9 phantom catalog companions unlinked, cygni relink to
  the corporation page, wrong design-doc path); wiki/index.md counts fixed
  (301 systems) + Economics nav section; corporations/index.md regenerated
  from frontmatter (all 155, tier1.toml grouping — corrects 4 misfiled
  tier-1 corps); 25 orphaned station GTTRs linked from 11 system pages
  (own ##-heading so atlas sync cannot absorb it); GOVERNANCE.md +
  star-system template rewritten to the generated model (DB owns
  structured fields, wiki owns prose); triangles/index.md added
- Sol markers conversion REVERTED before commit: atlas_viewer.gd:433 still
  renders the legacy geometry schema, so conversion would drop Sol's Atlas
  overlays — split to T-1073 (convert together with the client read path)

Broken relative links: 2,180 → 25 (all remaining are intentional
_templates/ placeholders).

+# Triangles
+
+Relationship triangles — three-character social structures whose internal tensions drive forks, escalations, and observable behavior shifts (D-024 NPC generation model). Each entry documents one triangle: its members, resting tension, fork paths, and the state tables that authoring and simulation reference. One worked example exists so far.
