Suggestion: Add knowledge-spread visualization tooling

[possibly]

Knowledge visualization is a powerful feature for understanding emergent narratives in Viv worlds. I built a tool (viv-knowledge-diagrams) that visualizes three key perspectives:

1. Knowledge tree - How knowledge of a specific action spread through characters (who told whom)
2. Memory map - What a character knows and how they learned it (witnessed vs. secondhand)
3. Propagation wave - Temporal waves of knowledge spread

Example of a memory map diagram:

◉ Varr — 133 memories (11 secondhand)

  Witnessed (122):
    retell-market-drama  sal:6  t=1740
    hold-court-from-bench  sal:4  t=300

  Learned secondhand (11):
    whisper-rumor-about  sal:5  t=1620  <- heard via elder-recounts-old-tale

This fills a gap. Viv already has built-in support for visualizing the causal graph (who did what, and what caused what). But there's no built-in way to visualize the knowledge layer: who remembers what, how they learned it, and how information spread through the world.

Having this as an official tool would help:

• Authors understand if their knowledge-relaying actions are working as intended
• Researchers study how knowledge spreads in procedural worlds
• Debuggers trace knowledge formation bugs

The tool is language-agnostic (works with any Viv adapter) and minimal (just reads from the runtime state). It might be worth including in the official toolkit or linking from the Viv docs.

@possibly Wow, this is awesome! I'll find some time soon to take a look over viv-knowledge-diagrams, and then consider how these ideas could make their way back into the official project.
