dsh-plugin-reducer v0.3.1

This prerelease completes the reducer's public distribution and maintenance
path without weakening its evidence gate.

Highlights

Install directly from the npm next channel or the matching pinned GitHub
Release artifact.
Publish from GitHub Actions through npm OIDC trusted publishing, with no
long-lived registry token and with automatic provenance.
Keep new previews on next; npm's initial 0.3.0 latest assignment is a
bootstrap artifact, not a stability signal, and is advanced only after three
independent, privacy-reviewed field reports satisfy the stable-release gate.
Validate machine envelopes against the shipped schemas and provide a pinned
Node consumer example.
Run the supported cross-platform CI matrix plus a scheduled Harness next
profile-layout canary.
State the product boundary explicitly: this is an external diagnostic CLI,
not a bundle installed into the profile it is diagnosing.

npm install --global dsh-plugin-reducer@next
