Migrate to Webpack logger and improve test coverage

[ronakmaheshwari]

**Summary**

Fixes #727

Adds missing test coverage for `analyzerMode: "server"` in `test/plugin.js`:
- Tests starting the analyzer server with `openAnalyzer: false` and `analyzerPort: "auto"`, verifying that the server starts listening and invokes `analyzerUrl` with the bound host and port.
- Tests reusing the plugin instance across multiple compiler configurations in `server` mode, verifying that `updateChartData` is called with the subsequent compiler's bundle directory (covering the logic introduced in #725).
- Ensures proper resource cleanup of HTTP and WebSocket servers across test runs.

Walkthrough

The changes add server-mode test coverage. The tests verify that analyzerUrl receives the server address and that reused plugin instances update chart data for the second compilation. A changeset announces a minor release and documents use of Webpack’s infrastructure logger and deprecation of logLevel.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 6da22

The server-mode coverage verifies the reused-plugin update path, with no concrete merge-blocking risk identified.
