Add workflow to bump v1 tags to main

[adityamaru]

Summary

Adds a workflow_dispatch workflow that updates both v1.0.0-beta and v1 tags to point to the head of main.

Usage

Trigger manually from Actions tab. No inputs required - it always targets the head of main.

---

Note

Medium Risk
Force-pushes moving git tags (v1/v1.0.0-beta), which can impact consumers that pin those tags, but is isolated to a manual CI workflow.

Overview
Adds a new manually triggered GitHub Actions workflow (.github/workflows/release-v1.yml) that checks out main and force-updates the v1.0.0-beta and v1 tags to point at HEAD.

The workflow also configures the Actions bot as the git author and writes the updated tag SHAs to the job summary.
