… proxies (#4316)

* fix: never proxy hot-reload websocket requests

Both create-react-app and vue-cli-service have introduced workarounds for this, but it seems to me that this is always desirable behaviour for webpack-dev-server.

* test(proxy-option): extend HMR upgrade coverage to URL variants of the configured path

Adds trailing slash, case variations, percent-encoded path, and
leading double slash to the existing HMR/proxy isolation tests so
that all URL shapes recognized as the HMR upgrade are treated
consistently.

* fix(proxy): normalize HMR upgrade path comparison

Tighten the HMR-vs-proxy upgrade dispatch so URL variants of the
configured HMR path are consistently recognized as the HMR socket:

  - lowercase comparison (case-insensitive)
  - decode percent-encoding before comparison
  - strip trailing slashes
  - collapse leading multiple slashes so //foo is treated as /foo
    instead of being parsed as a scheme-relative URL
  - wrap URL parsing in try/catch so a malformed req.url does not
    raise an uncaught exception

* fix(proxy): enforce exact HMR upgrade path matching for websocket connections

* fix(proxy): improve HMR upgrade path handling and user proxy integration

* ci: pin node 24

* fix(test): update Node.js version matrix and adjust test naming for clarity

* fix(proxy): enhance HMR upgrade handling by improving WebSocket server management
