ci: publish vendor-bundled release ZIP

[chubes4]

Summary

• Adds a build-release-asset follow-up job to the Homeboy workflow when Homeboy creates a release.
• Builds the release tag with Composer production dependencies, the wp-scripts admin bundle, and uploads data-machine.zip to the GitHub Release.
• Stages a clean plugin directory with runtime files only, excluding tests, docs, GitHub metadata, Node modules, and dev configs.

Issue

• Fixes Publish vendor-bundled release artifact for public installability #2029

Validation

• composer install --no-dev --optimize-autoloader --prefer-dist --no-interaction
• npm ci
• npm run build
• Locally staged and zipped dist/data-machine.zip, extracted it, and verified it contains data-machine.php, inc/, vendor/autoload.php, and built admin assets under inc/Core/Admin/assets/build/.
• Verified extracted ZIP excludes tests/, docs/, .github/, node_modules/, package.json, package-lock.json, and phpstan-baseline.neon.
• ruby -e 'require "yaml"; YAML.load_file(".github/workflows/homeboy.yml")'

Notes

• homeboy audit reports existing repo-wide heuristic findings unrelated to this workflow-only change.
• homeboy lint reports existing repo-wide lint findings unrelated to this workflow-only change.
• homeboy test currently fails before tests run in the local environment because the local dependency load is missing WP_Agent_Principal_Access_Store from Agents API/Data Machine bootstrap.
