- Zod schema: validate relayBindHost with ipv4/ipv6 instead of bare string
- Upgrade handler: allow non-loopback connections when bindHost is explicitly
non-loopback (e.g. 0.0.0.0 for WSL2), keeping loopback-only default
- Test: verify actual bind address via relay.bindHost instead of just checking
reachability on 127.0.0.1 which passes regardless
- Expose bindHost on ChromeExtensionRelayServer type for inspection

Add browser.relayBindHost config option so the Chrome extension relay
server can bind to a non-loopback address (e.g. 0.0.0.0 for WSL2).
Defaults to 127.0.0.1 when unset, preserving current behavior.

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

Two pre-existing tests still expected ws:// URLs to be rejected by
parseHttpUrl, which now accepts them. Switch the invalid-protocol
fixture to ftp:// and tighten the assertion to match the full
"must be http(s) or ws(s)" error message.

- Add 12 new tests covering: isWebSocketUrl detection, parseHttpUrl WSS
acceptance/rejection, direct WS target creation with query params,
SSRF enforcement on WS URLs, WS reachability probing bypasses HTTP
- Reframe docs section as generic "Direct WebSocket CDP providers" with
Browserbase as one example — any WSS-based provider works
- Update security tips to mention WSS alongside HTTPS

Browserbase uses direct WebSocket connections (wss://) rather than the
standard HTTP-based /json/version CDP discovery flow used by Browserless.
This change teaches the browser tool to accept ws:// and wss:// URLs as
cdpUrl values: when a WebSocket URL is detected, OpenClaw connects
directly instead of attempting HTTP discovery.
Changes:
- config.ts: accept ws:// and wss:// in cdpUrl validation
- cdp.helpers.ts: add isWebSocketUrl() helper
- cdp.ts: skip /json/version when cdpUrl is already a WebSocket URL
- chrome.ts: probe WSS endpoints via WebSocket handshake instead of HTTP
- cdp.test.ts: add test for direct WebSocket target creation
- docs/tools/browser.md: update Browserbase section with correct URL
format and notes

Only restore env vars when we actually modified them (noProxyDidModify
flag). Prevents silently deleting a user's NO_PROXY that already
contains loopback entries. Added regression test.
Fix Greptile review: when call A exits before call B, the isFirst flag
on B is false, so the restore condition (refCount===0 && isFirst) was
never true and NO_PROXY leaked permanently.
Remove '&& isFirst' so any last exiter (refCount===0) restores the
original env vars. Added explicit reverse-exit-order regression test.
Address Greptile review feedback:
- Replace snapshot/restore pattern with reference counter to prevent
permanent NO_PROXY env-var leak under concurrent async calls
- Include [::1] in the alreadyCoversLocalhost guard
- Add concurrency regression test
When HTTP_PROXY / HTTPS_PROXY / ALL_PROXY environment variables are set,
CDP connections to localhost/127.0.0.1 can be incorrectly routed through
the proxy (e.g. via global-agent or undici proxy dispatcher), causing
browser control to fail.
Fix:
- New cdp-proxy-bypass module with utilities for direct localhost connections
- WebSocket (ws) CDP connections: pass explicit http.Agent to bypass any
global proxy agent patching
- fetch-based CDP probes: wrap in withNoProxyForLocalhost() to temporarily
set NO_PROXY for the duration of the call
- Playwright connectOverCDP: wrap in withNoProxyForLocalhost() since
Playwright reads env vars internally
- 13 new tests covering getDirectAgentForCdp, hasProxyEnv, and
withNoProxyForLocalhost (env save/restore, error recovery)
