[BUG] Claude Desktop → Claude in Chrome: navigate fails with "Navigation to this domain is not allowed" on all domains, no permission prompt shown[BUG]

What's Wrong?

Every browser navigate action issued from Claude Desktop through the Claude in Chrome integration fails immediately with "Navigation to this domain is not allowed" — for every domain tested, including neutral ones like example.com and google.com. No permission prompt/dialog ever appears in Chrome for the user to approve the domain. Other interactive actions (keyboard input, clicking) fail the same way with "Permission denied for this action on this domain."

What Should Happen?

Navigation should either succeed, or Chrome should show a permission prompt asking the user to approve the domain before Claude Desktop acts on it.

Error Messages/Logs

Navigation to this domain is not allowed
Permission denied for this action on this domain

Steps to Reproduce

1. Install/connect the Claude in Chrome extension, signed in with the same account as Claude Desktop.
2. In Claude Desktop, ask Claude to navigate the browser to any URL (e.g. "go to example.com").
3. Observe: "Navigation to this domain is not allowed" — no popup appears in Chrome.

Note: The same extension works correctly when driven directly from its own side panel inside Chrome (e.g. asking it there to visit facebook.com succeeds immediately, confirmed action taken).
Note: Re-pairing the browser (via the Chrome integration card in Claude Desktop, "Install"/reconnect) produces a fresh device pairing (new deviceId) but does not fix the issue.
Note: Tab management (listing/creating tabs) works fine through the same connection — only interactive actions (navigate, click, type) fail.
Note: Chrome extension's own "Site access" permission is set to "On all sites" (most permissive). No domain-level allow/deny rules exist in any Claude Code settings.json.
