Add release workflow with GitHub release and NuGet publishing

[Copilot]

Release Workflow Implementation

• Explore repository structure and existing workflows
• Create release.yaml workflow file with:
  • workflow_dispatch trigger with version and publish inputs
  • Build job using the reusable build.yaml workflow on ubuntu-latest
  • Release job on ubuntu-latest with conditional release and publish steps
• Verify workflow file passes YAML linting
• Manual validation of workflow structure
• Address code review feedback:
  • Use consistent dotnet-version format
  • Include all supported dotnet versions (8.x, 9.x, 10.x)
  • Add --skip-duplicate flag to NuGet push command
  • Add error handling (set -e) to NuGet push command
  • Update version input description to show example format
• Request final code review
• Run security scan (no issues found)

<issue_title>[Feature]: Release Script</issue_title>
<issue_description>### Problem Statement

The ReqStream tool needs a release workflow.

Proposed Solution

Add a release.yaml file that:

• Is executed on workflow-dispatch
• Has a required 'version' input for specifying the release version string
• Has a required 'publish' input choice for picking the publish type (none, release, or publish)
• Runs a 'build' job (using the build.yaml reusable workflow) on ubuntu-latest
• Runs a 'release' job on ubuntu-latest which:
  • Installs dotnet 10.x
  • Downloads the build artifacts
  • If the 'publish' input is 'release' or 'publish' then run ncipollo/release-action to publish the artifacts and generate release notes, and tag the repository with the 'version' input
  • If the 'publish' input is 'publish' then run dotnet nuget push to push the nupkg file to nuget.org using the 'DEMACONSULTINGNUGETKEY secret.
