Add automated release workflow for version tags

[jamespepper81]

Summary

Adds a GitHub Actions workflow that automatically creates releases when version tags are pushed to the repository. The workflow extracts release notes from the CHANGELOG.md file, detects prerelease versions (alpha/beta/rc), and creates GitHub releases with appropriate metadata.

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update
• Refactor / cleanup

Details

The new release.yml workflow:

• Triggers on pushes to tags matching the pattern v*
• Extracts the version number from the tag
• Detects prerelease versions based on tag suffixes (alpha, beta, rc)
• Parses release notes from CHANGELOG.md for the corresponding version
• Falls back to a generic release message if version notes aren't found
• Creates a GitHub release with the extracted metadata using softprops/action-gh-release

This enables automated release management without manual intervention when version tags are created.

Test Plan

The workflow will be tested when the first version tag is pushed to the repository. The workflow can also be validated by:

1. Verifying the workflow syntax is correct (GitHub will validate on push)
2. Checking that the CHANGELOG.md parsing logic correctly extracts version sections
3. Confirming prerelease detection works for tags like v1.0.0-alpha, v1.0.0-beta, v1.0.0-rc
