v1.3.12

Adds beginner mode to the CFOP solver.

Changes:

• CfopSolverOptions gains a beginner?: boolean flag. When true, the solver produces a 9-stage solution instead of 7: intuitive F2L (fluid priority loop — works on whichever pair is easiest at each step, inserts via standard triggers like R U R' and L' U' L), 2-look OLL (orient edges first, then corners), and 2-look PLL (permute corners first, then edges).
• Fixed a bug where PLL skip cases that required an AUF (e.g. U') had the rotation dropped from the solution.
• Fixed the EOLL dot algorithm — the previous alg was incorrect in the solver's z2 frame.
