[BUG] Claude in Chrome incorrectly blocks solar-stack.com as restricted domain

Description

Claude in Chrome extension blocks all interaction with solar-stack.com, showing "This site is blocked by your organization's policy" error. The site appears to be incorrectly classified as a restricted category.

Evidence

• navigate, computer (screenshot), read_page, javascript_tool — all return "This site is blocked by your organization's policy"
• tabs_context_mcp works — shows the page is loaded with correct title and URL
• Same codebase works on the Vercel preview subdomain (.vercel.app) — navigate, screenshot, read_page all succeed
• No Chrome enterprise policies set (chrome://policy/ shows empty)
• No blocking extensions (tested with all disabled)
• curl confirms site returns 200 OK with server: Vercel

Console errors on the site

Executing inline script violates the following Content Security Policy directive 'script-src 'self' 'wasm-unsafe-eval' 'inline-speculation-rules''
Unchecked runtime.lastError: Debugger is not attached to the tab with id: 273919879
Could not establish connection. Receiving end does not exist.

Note: CSP violation is from the extension's own Manifest V3 CSP, not the site's headers. The site includes 'unsafe-inline' in its CSP script-src.

Steps to reproduce

1. Open Claude Code CLI
2. Connect Chrome extension via /chrome
3. Try navigate to https://www.solar-stack.com/
4. Get "This site is blocked by your organization's policy"
5. Try navigate to the same app on its .vercel.app subdomain — works fine

Expected behavior

The extension should allow interaction with solar-stack.com — it is not a financial, banking, or adult site.

Environment

• Claude Code: latest
• Chrome extension: Claude in Chrome Beta
• Chrome: 145.x
• OS: Linux (Fedora 43)
