feat: add tree-shakeable asyncPipe export

[ericelliott]

• Remove non-existent root export from package.json

• Add './asyncPipe' subpath export with TypeScript definitions

• Create lib/asyncPipe.d.ts with proper function signatures

• Install TypeScript and add typecheck npm script

• Add automated tests verifying import paths (lib/exports.test.js)

• Update docs/server/README.md to use 'aidd/asyncPipe' import path

• Archive completed library-exports-epic task

---

Note

Introduce tree-shakeable aidd/asyncPipe export with TS typings; update docs, add tests, and set up type checking.

• Exports:
  • Add ./asyncPipe subpath in package.json with types (lib/asyncPipe.d.ts) and default (lib/asyncPipe.js).
  • Remove root export and add types mapping for ./server.
• Type Definitions & Tooling:
  • Add lib/asyncPipe.d.ts with overloads.
  • Add typescript dev dependency, typecheck npm script, and tsconfig.json for type-only checks.
• Tests:
  • Add lib/exports.test.js to verify aidd/asyncPipe import, function composition, aidd/server exports, and package.json exports config.
• Docs:
  • Update docs/server/README.md to import asyncPipe from aidd/asyncPipe.
• Project Tasks:
  • Mark library exports epic as completed (tasks/archive/library-exports-epic.md).
