ci: skip mutation tests on PRs with no TS source changes#622
Merged
Conversation
Add a check-code-changes job that diffs the PR against the base branch and sets an output flag when .ts files under vscode-extension/src/ or vscode-extension/test/, or stryker.config.mjs, are modified. The mutation-testing job now depends on check-code-changes and only runs when vscode_src_changed == 'true', skipping it for docs, JSON data files, workflows, and other non-code changes.

Summary
Mutation tests are expensive (~60 min). This PR avoids running them on PRs that don't touch any TypeScript source code in the VS Code extension.
