Foundry: Modern Addon Library and Ace3 Alternative

[1.0.111] - 2026-10-21

Fixed

• Foundry.List now refuses a NaN or infinite config.extent, and handles a NaN or infinite value from extentCalculator the same way, matching how it already treated zero and negative values. Dev builds raise an error. Release builds print a message and then refuse the list (config.extent) or fall back to an extent of 1 (extentCalculator).

Changed

• The TOC notes and README now describe Foundry as a modern addon library and Ace3 alternative.
