ci: trigger releases on tag push, replace deprecated set-output and release actions

[erwan-joly]

• on: create → on: push: tags (create fires on every branch creation; the tag filter isn't honored)
• ::set-output (removed by GitHub) → $GITHUB_OUTPUT
• checkout@v2 / setup-dotnet@v3 (retired node16 runtime) → checkout@v4 / setup-dotnet@v5
• jossef/action-latest-release-info + archived actions/upload-release-asset@v1 → softprops/action-gh-release@v2 (the old pair attaches the nupkg to the previous release when the new tag has none yet)
• tag name from GITHUB_REF, explicit permissions: contents: write

SDK stays 8.0.x — the analyzer targets netstandard2.0. Test command unchanged. Same pattern as NosCore.Packets.

Walkthrough

The GitHub Actions workflow now builds and publishes the .NET package for matching version tags. It uses updated actions, modern output handling, tag-derived artifact names, and softprops/action-gh-release@v2.

Changes

Package release workflow

Layer / File(s)	Summary
Workflow setup and tag validation .github/workflows/dotnet.yml	The workflow runs for *.*.* tags and pull requests to master. The build job has contents: write permission. The workflow uses updated checkout and .NET setup actions. Tag validation uses the refs/tags/ pattern and GITHUB_OUTPUT.
Package build and release .github/workflows/dotnet.yml	The build step derives the package name from GITHUB_REF and exports ARTIFACT_PATH. The workflow removes latest-release lookup and uploads the artifact with softprops/action-gh-release@v2.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to abdab

This workflow now performs tag-driven package publication and GitHub release updates with write-capable credentials. The current implementation can execute crafted tag input in a privileged shell and expose persisted write credentials to repository-controlled build or test steps, potentially affecting repository or package integrity; it can also fail for tags that do not match the fixed package version. Merge should be blocked until these issues are fixed.

In @.github/workflows/dotnet.yml:
- Line 43: Update the dotnet pack invocation in the workflow to set
PackageVersion from TAG_NAME, ensuring the generated NosCore.Analyzers package
filename matches the path used by the dotnet nuget push step.
- Line 16: Update the actions/checkout@v4 step in the workflow to set
persist-credentials to false, preventing the checkout token from remaining
available to subsequent build or test commands.
- Around line 13-14: Split the workflow into separate build/validation and
release jobs: configure the build job with contents: read, and scope contents:
write exclusively to the tag-triggered release job. Keep validation commands in
build and release commands in the release job, preserving their existing
triggers and behavior.
- Line 25: Update the tag-validation condition in the workflow step to read the
ref through the runner-provided environment variable instead of interpolating
github.ref directly into Bash source, while preserving the existing
semantic-version tag pattern.
