Pull request overview

This PR introduces a dedicated GitHub Actions workflow for manual / release-triggered npm publishing, and updates project docs and metadata to reflect recent feature additions (multi-provider LLM support, new CLI commands, and new hooks).

Changes:

• Add .github/workflows/npm-publish.yml with workflow_dispatch and an explicit npm run build before npm publish.
• Update docs/README/CLAUDE.md/CHANGELOG.md content around trailers, hooks, and multi-provider LLM configuration.
• Adjust an integration test to use GIT_MEM_MODEL instead of ANTHROPIC_MODEL under CLAUDECODE.

.github/workflows/npm-publish.yml:20

• Repo workflows consistently use Node.js 22 (ci.yml, release-on-merge.yml). This workflow pins Node 20 and also omits the cache: 'npm' setting used elsewhere, which increases CI time and can hide Node-version-specific issues. Align node-version with the rest of the repo and enable npm caching via setup-node.

      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm ci
      - run: npm test

.github/workflows/npm-publish.yml:2

• The header comment says this publishes to GitHub Packages, but the job config uses the npm registry (registry-url: https://registry.npmjs.org/) and runs npm publish. Update the comment to avoid confusion about where artifacts are being published.

# This workflow will run tests using node and then publish a package to GitHub Packages when a release is created
# For more information see: https://docs.github.com/en/actions/publishing-packages/publishing-nodejs-packages

This workflow triggers on release: created, but the repo already publishes via semantic-release on push to main (release-on-merge.yml) and creates GitHub releases. When semantic-release creates a release, this workflow will also run and attempt a second npm publish, which will likely fail (version already published) and adds operational noise. Consider removing the release trigger and keeping only workflow_dispatch, or otherwise ensure it won’t double-publish (e.g., guard conditions / use a different registry or artifact source).
