pattern matching

SKILL.md

Pattern matching replaces ALL imperative control flow in Effect code. There should be ZERO if/else statements, switch/case blocks, or ternary operators in idiomatic Effect code.

| if/else chains | Match.value + Match.when | | switch/case statements | Match.type + Match.tag | | Ternary operators (? :) | Match.value + Match.when | | Null checks | Option.match | | Error checks | Either.match or Effect.match | | Type guards | Match.when with Schema.is() |

When you encounter imperative control flow, refactor it to pattern matching immediately.
