PR Summary

Medium Risk
Changes the CI/CD release automation by adding a new workflow that commits to main and creates tags based on merged PR labels, which can impact versioning and publish cadence if misconfigured.

Overview
Adds a new GitHub Actions auto-release workflow that runs on pushes to main, finds the latest stable vX.Y.Z tag, determines patch vs minor bumps based on whether the merged PR has a patch label, then updates package.json, commits, and pushes a new v-prefixed tag (skipping runs triggered by weka-version-bumper[bot]).

Updates DEVELOPER_SETUP.md and VERSIONING.md to reflect the new automatic publishing process (minor-by-default on merge, patch via patch label, major via manual tag), replacing the previous manual release command guidance.
