fix(browser): rewrite 0.0.0.0 and [::] wildcard addresses in CDP WebSocket URLs

Browse Source 
Containerized browsers (e.g. browserless in Docker) report
`ws://0.0.0.0:<internal-port>` in their `/json/version` response.
`normalizeCdpWsUrl` rewrites loopback WS hosts to the external
CDP host:port, but `0.0.0.0` and `[::]` were not treated as
addresses needing rewriting, causing OpenClaw to try connecting
to `ws://0.0.0.0:3000` literally — which always fails.

Fixes #17752
