• Introduce a new tracer workspace with its own VariableTracer implementation and exports.
• Rewire imports in dependent packages (estree-ast-utils, root code) to use @nodesecure/tracer.
• Remove VariableTracer exports and related tests from estree-ast-utils.

workspaces/tracer/package.json:1

• There are currently no tests in the tracer workspace. Consider adding unit tests for VariableTracer methods to ensure its behavior is validated and prevent regressions.

workspaces/tracer/src/VariableTracer.js:14

• Ensure that the ./utils/index.js path exists in this workspace and is included in the package. It looks like the utils directory or its index may not have been created, which would break these imports.
