feat: add npx/bunx binary distribution support

Adds infrastructure for distributing Hapi via npm as a scoped package
(@twsxtd/hapi) with platform-specific optional dependencies. This enables
installation via `npx @twsxtd/hapi` or `bunx @twsxtd/hapi`.

- Add bin/hapi.js wrapper script for platform detection and binary selection
- Create npm/ directory structure for platform-specific packages (darwin-{arm64,x64},
  linux-{arm64,x64}, win32-x64)
- Add scripts/prepare-npm-packages.ts to generate platform-specific package.json files
  and copy binaries to npm packages
- Add scripts/publish-npm.ts for automated publishing of platform packages
- Update package.json with new scoped name, bin entry, optionalDependencies, and
  prepack/publish scripts
- Update .gitignore to ignore generated npm packages and build outputs
- Update .npmignore to only include bin/hapi.js wrapper, excluding source and build files
