Pull request overview

This PR fixes a false positive warning that occurs when provide() is called during HMR (Hot Module Replacement) updates on already-mounted component instances. The warning "provide() can only be used inside setup()" was incorrectly triggered during legitimate HMR reloads, particularly in components like router-view that call setup during re-renders.

• Adds HMR context check to suppress provide() warning during hot updates
• Includes test coverage for the router-view-like scenario where setup is re-executed on HMR reload
