Support hot-loading Chrome tools mid-session via /chrome

Description

Running /chrome mid-session allows toggling the Chrome integration setting (enabled/disabled), but does not actually load the Chrome browser tools into the current session. The tools are only available if the session was started with claude --chrome or if "Enabled by default" was set before starting the session.

Expected behavior

Running /chrome and enabling Chrome integration should make Chrome browser tools available in the current session without requiring a full restart. This could be implemented as:

• Hot-loading the tools into the running session, or
• Automatically exiting and resuming the session with Chrome enabled (preserving conversation context)

Current behavior

• /chrome opens a menu to manage permissions, reconnect extension, and toggle "Enabled by default"
• Toggling the setting and reconnecting does not load Chrome tools into the running session
• /context still shows no Chrome tools after enabling
• User must exit and restart with claude --chrome to get Chrome tools

Environment

• Claude Code v2.1.92
• Linux (Ubuntu)
• Chrome extension installed and detected (Extension: Installed)

Workaround

Exit the session and restart with claude --chrome, or set "Enabled by default: Yes" so all future sessions include Chrome tools.
