fix(node-api): decode percent-encoded path before process.dlopen

`URL.pathname` is percent-encoded, but `process.dlopen` expects a filesystem
path. Any space in the package's path therefore reaches dlopen as "%20" and the
addon fails to load:

    TypeError: dlopen(/Applications/My%20App.app/.../NativeScript, 0x0001):
      tried: '.../My%20App.app/...' (no such file)

This breaks every packaged app whose path contains a space — for example an
.app installed to /Applications with a display name like "My App.app". It goes
unnoticed in development because the package normally resolves from a
node_modules path with no spaces, where decoding is a no-op; only a distributed
bundle exercises the failing path.

Wrap the resolved pathname in decodeURIComponent() at all three dlopen sites:

  - packages/macos-node-api/index.mjs
  - packages/macos-node-api/index.cjs
  - packages/ios-node-api/index.js

Verified on macOS by copying packages/macos-node-api together with its built
NativeScript.framework into a directory whose name contains a space, then
importing it under Deno:

  - before: dlopen fails with the %20 path shown above
  - after:  the addon loads and init() runs

Note: paths containing "#" or "?" are still mishandled, because the base URL is
built by string concatenation and those characters are parsed as fragment/query
delimiters. Spaces are by far the common case; a complete fix would resolve the
addon path without going through URL at all.
