ci: trigger releases on tag push instead of the create event

[erwan-joly]

Aligns with the NosCore.Packets workflow pattern:

• on: create → on: push: tags — create fires on every branch creation and its tag filter isn't honored
• tag name from GITHUB_REF (github.event.ref only exists on the create event)
• actions/checkout@v4

Build/test steps unchanged.

Summary by CodeRabbit

• Chores
  • Updated automated build and release workflows to run only for pushes, version tags, and pull requests targeting the main branch.
  • Improved version tag detection and package naming for generated build artifacts.
  • Removed unnecessary artifact output handling.

Walkthrough

The GitHub Actions workflow now handles version-tag releases through push references. It validates semantic-version tags with github.ref and uses the extracted tag name for package filenames, NuGet publishing, and artifact paths.

Changes

Release workflow

Layer / File(s)	Summary
Tag validation and package publishing .github/workflows/dotnet.yml	The workflow matches semantic-version push tags through github.ref. The build step extracts TAG_NAME from GITHUB_REF and uses it for the package filename, NuGet push, and artifact path.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to ed433

Tag pushes now initiate package and GitHub release publication, but the current workflow evaluates the tag as shell syntax before validating it, allowing an authorized tag pusher to affect the release runner and publication steps. The workflow also derives the package path from the tag while the project version remains fixed at 6.0.1, so other valid-looking tags can produce failed or inconsistent releases; these issues should be fixed before merging.

Inline comments:
In @.github/workflows/dotnet.yml:
- Line 25: Update the tag condition in the workflow to avoid interpolating
github.ref directly into Bash source; pass the ref through an environment
variable and evaluate that variable in the regex check, preserving the existing
semantic-version tag filter.
- Line 46: Update the workflow’s tag validation to read GITHUB_REF from the
environment rather than interpolating it directly into the shell conditional,
preventing command substitution before regex validation. Also update the dotnet
pack invocation to pass PackageVersion from TAG_NAME so the generated package
filename matches the subsequent dotnet nuget push path.
