Pull request overview

This PR updates GitHub issue templates to be more dynamic and adds automation to keep version dropdowns in sync with repository releases/package version, plus some related repo tooling updates.

Changes:

• Added a PowerShell sync script and pre-commit hook to auto-update issue template “Package Version” dropdowns from package.json, CHANGELOG.md, git tags, and release tags.
• Expanded/adjusted issue forms (bug/feature/docs) with additional fields (severity, regression, Unity version dropdowns) and fixed the Discussions contact link.
• Added a GitHub Actions workflow to sync templates on main changes/releases; updated sync-banner-version.ps1 to also sync .llm/context.md.
