v2.0.1

Fixed

• ex_ast dependency — ex_ast is now a regular dependency instead of only: [:dev, :test]. Pattern smell checks import ExAST at compile time, so the previous declaration made Reach uninstallable from Hex. (Fixes #14)

Improved

• Smell false positive reduction — narrowed loop antipatterns to accumulator loops and recursive operands, excluded compile-time constructs and formatting functions from redundant computation, removed debatable patterns (chained String.replace, Enum.take with negative count, sequential Enum.filter). Validated on 19 Hex packages: 63% fewer findings, all remaining verified as true positives.
• Module documentation — all public modules now have @moduledoc descriptions.
