Description

Implement the Map ujsx component function. Represents mapping over an array — creates one child instance per array item. Structurally equivalent to a dynamically-generated Parallel group.

Acceptance Criteria

• src/component/map.ts exports Map component function
• Map produces UElement with type: "map"
• Props: over: Signal<unknown[]> | unknown[] | ((results: Record<string, CallResult>) => unknown[]) (required), as: string (required), children: UNode (required — template rendered per item)
• The as prop names the variable each item is bound to
• Aggregate completion semantics: all mapped nodes must reach satisfying terminal state for Map to be "completed"; any failed/aborted child makes Map failed/aborted
• Re-exported from src/component/index.ts
• Unit tests: correct UElement shape with each over form (static, function), as prop preserved
