Support multiple account switching for Max/Pro subscriptions

Problem

Claude Code currently requires /logout + /login (browser-based, interactive) to switch between accounts. Users with both personal and work Max/Pro subscriptions need to go through this flow every time they want to switch — there's no way to automate or speed it up.

Suggested Solution

Some form of multi-account/profile support, e.g.:

• claude /accounts — list saved accounts and switch between them
• claude --profile work — launch with a specific profile
• Per-directory account binding (e.g., via .claude/config or similar)

Context

• API key auth (ANTHROPIC_API_KEY) works for API-billed accounts but not for Max/Pro subscriptions
• The browser-based OAuth login flow can't be scripted or automated
• This is a common need for developers who use Claude Code for both personal and work projects
