Claude in Chrome: extension never connects on Linux; /chrome reconnect flashes a tab and closes it

Claude Code 2.1.281 (npm/nvm install), extension 1.0.94, Google Chrome on Linux (AWS WorkSpace). Chrome and Claude Code run on the same machine.
The same claude.ai account is signed in to both the CLI and the extension.
/chrome → reconnect opens a tab in Chrome that closes immediately. Afterwards /chrome reports: Couldn't list connected browsers: JSON Parse error: Unexpected identifier "Browser".
Browser tools return "Browser extension is not connected".
The native host is registered (~/.config/google-chrome/NativeMessagingHosts/com.anthropic.claude_code_browser_extension.json), running (claude.exe --chrome-native-host) and listening on /tmp/claude-mcp-browser-bridge-<user>/<pid>.sock, but the CLI process never connects to that socket (ss -xp shows no peer).
The username has a domain suffix which appears in the socket directory name.
It worked on earlier versions and stopped around 2026-09-23.
