[FEATURE] Add centralized session/token management dashboard for Claude Code Max subscribers

Problem Statement

As a Claude Code Max subscriber using claude setup-token across multiple devices, there is currently no way to audit, view, or revoke active sessions from a single place.

Current behavior

• claude setup-token generates an OAuth token stored locally on each device
• Token storage varies by platform (macOS Keychain, libsecret on Linux, plain file on headless systems)
• No CLI command or web dashboard to list all active tokens/sessions tied to my subscription
• No way to revoke a specific device's token remotely
• No visibility into how many concurrent session slots are in use

The problem

I use Claude Code across 4+ devices — macOS terminal, Android (Termux), and 2 Ubuntu VMs. To audit which devices are authenticated, I have to SSH into each machine and check platform-specific credential stores individually. If a device is lost or compromised, there's no quick way to revoke just that token without accessing the device itself.

Additional context

This becomes more critical when using setup-token to authorize third-party tools (e.g., AI agent platforms that consume the subscription via the token). Without centralized visibility, subscribers lose track of what's authorized to use their account.

Proposed Solution

Proposed solution

A session management panel (on claude.ai/settings or console.anthropic.com) that shows:

1. Active sessions list — device name/hostname, platform, token creation date, last active timestamp
2. Revoke individual tokens — invalidate a specific device without affecting others
3. Concurrent usage visibility — current active slots vs plan limit
4. Usage breakdown per device — token consumption per session (optional)

Prior art

• GitHub → Settings → Sessions
• Google → Security → Your Devices
• Slack → Settings → Active Sessions

These are standard for any subscription service that supports multi-device authentication.
