Node consumer example

This is a deliberately small downstream project that installs the pinned, verified v0.3.1 release and consumes the public library API. It never modifies the source Harness profile; the reducer creates disposable shadow profiles for its probes.

cd examples/node-consumer
npm install
DSH_HOME=/path/to/.dsh npm start

PowerShell:

cd examples/node-consumer
npm install
$env:DSH_HOME = "$HOME\.dsh"
npm start

Set DSH_PROFILE when the failing profile is not web, or DSH_COMMAND when the dsh executable is not on PATH. Successful output is one JSON line with the minimal set plus the complete redacted report.

The example intentionally pins a release URL. Change the dependency only after reviewing the target release notes and checksum.
