Occupied tiles now block movement through World::blocked, the one predicate
the sim and the pathfinder share. Entities carry an EntityKind so the sim
knows which ones to think for; Sim::think gives each NPC a random king move
one window in four. Intents execute in id order so contested tiles resolve
deterministically.

pbio moves to git.bnd.wtf/irrlicht/pbio.git branch truecolor16: the
framebuffer is now RGB565 u16, no palette. Assets are loaded from PNG via
the png crate and quantized to RGB565 on load; transparency comes from the
alpha channel as a per-tile opacity mask, so any color (black included) can
be opaque. The TGA loader and the palette-order fragility are gone.
overworld.png is the unmodified Mini-Medieval Overworld sheet (same 24-column
layout as the old TGA, so map tile ids are unchanged); entities.png holds the
player sprite extracted from the old entities.tga.
Adds an ignored snapshot test that renders the first frame headlessly to a
PNG for eyeballing the renderer without a window.
