refactor(data): rename Krenn to Van Maanen's Star

System S-057 assigned to real star GJ 35 (Van Maanen's Star, DG white
dwarf at 13.9 ly). Renamed across all content, server code, docs,
decisions, wiki lore, and config files. 224 files updated.

 The short answer: **through a society profile assembled from combinatorial ingredients, not through per-world hand-authoring**.
 
-The longer answer follows from what I established in Wiki Review Round 4. The Krenn System brief (Rounds 1-2 of that workshop) was a proof of concept — one complete output. Round 4 inverted the question: instead of writing a brief for each world, we design the *ingredient pantry* from which any brief can be generated.

 **4. Social site character:** Same template type (logistics district), different NPC population distribution. Vareth's higher philosophical alignment (labor-solidarity) increases ANCHOR and SYSTEM pattern counts — more community pillars, more institutionalized labor representation. Sova's null philosophical alignment produces more NOBODYs and CIVILIANs — the grey economy is moral shelter, not ideology.

 **6. Access topology** (the investigation architecture): Vareth's higher Meridian coverage and better-maintained infrastructure means fewer natural dead zones. The ring (or equivalent grey economy) on Vareth had to BUILD its dead zones rather than exploit existing gaps. This affects which locations are grey-economy-accessible and how the spatial investigation works.

 Miri's additional question (for me): "Are the cultural variation axes sufficient replayability levers, or do we need additional randomization within a cultural type?"
 
-My answer: **Sufficient for cross-world variety. Insufficient for within-world replayability.** The cultural parameters are fixed per world. Within-world replayability comes from the seed-driven NPC generation, triangle configuration, and entanglement assignment — which vary WITHIN the cultural parameters. A Frost/Salt/Iron culture with entanglement pattern A is a different game from the same culture with entanglement pattern B, even though both feel "Krenn-like." The within-culture variation is the replayability mechanism. The cultural composition is the setting — it's stable, not randomized per run.
