Add `matchEach` to ts-pattern

Normalized profile

What this task asks for

Add a new `matchEach` matcher that evaluates all matching clauses and returns all results in order. `matchEach` must expose the same builder API as `match`, including all `.with()` overloads (single pattern, multi-pattern, and guard variants), `.when()`, `.returnType()`, and `.narrow()`. Unlike `match`, every `.with()` call must accept patterns against the original input type (not the progressively narrowed remainder), since all branches are always evaluated. Exhaustiveness tracking should still narrow the internal type so `.exhaustive()` can verify all cases are handled, while `.narrow()` updates both the internal tracking type and the input type for subsequent calls to exclude handled cases. `.exhaustive()` additionally enforces compile-time exhaustiveness: it should be a type error if not all input cases are handled. `.toExhaustiveFunction()` behaves the same but additionally enforces compile-time exhaustiveness: it should be a type error if not all input cases are handled. Selections via `P.select()` must produce independent results across multiple calls of any compiled function.
