Use coverage-master for tag events to skip CloudFormation actions tests

[Copilot]

Description

Tag pushes trigger the lint-and-test workflow, which runs make coverage by default. This includes tests that validate CloudFormation actions against AWS endpoints, causing failures when the local actions list is stale during release workflows.

Changes

Modified .github/workflows/lint-and-test.yml to use make coverage-master for tag events:

• make coverage: Runs for feature branches and PRs (includes all tests)
• make coverage-master: Runs for master branch and tags (skips @pytest.mark.actions tests via -m "not actions")

Updated conditionals:

- run: make coverage
  if: github.ref != 'refs/heads/master' && !startsWith(github.ref, 'refs/tags/')

- run: make coverage-master
  if: github.ref == 'refs/heads/master' || startsWith(github.ref, 'refs/tags/')

Checklist

• I have updated the pyproject.toml

Pull request overview

This PR modifies the CI workflow to skip CloudFormation actions tests during tag-triggered builds. Tag pushes now use make coverage-master (which excludes tests marked with @pytest.mark.actions) instead of make coverage, preventing failures when the local CloudFormation actions list is stale during release workflows.

Changes:

• Updated conditional logic to run make coverage-master for both master branch and tag events
• Ensures feature branches and PRs still run full test coverage including actions tests
