anyCreature 1.3.1

Reads are scored, the brief is checked, and everything computable is computed.

• Gate 1 is scored by rank and view count instead of one exact word.
• Silhouettes are produced from the geometry; no browser in the LOW loop.
• value_order and contrast_adjacent replace the colour read; MID spends no reader.
• brief.py checks the brief for presence before the first round.
• New engine checks: soft_mass, gait_direction, root_drive. The L1–L8 shading
  stack runs inside the engine on every build.
• fit.py applies the arithmetic corrections the engine prints, before a round is
  spent.
• Publishing hands back a share link, a claim link and a one-time takedown code;
  the claim link is checked before it is shown.
