Cross-device session continuity for Claude Code

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

It would be very useful to be able to resume a Claude Code session from a different device (e.g. start on PC CLI, continue on mobile browser or vice versa).
Currently each session is isolated with no sync between devices. A simple session ID or link-sharing mechanism would allow users to pick up conversations regardless of the device used.

Proposed Solution

A session ID or shareable session link should be generated when starting a Claude Code session. Users could then resume the exact same session from any device (mobile browser, another PC, etc.) by providing this ID.
For example:
claude --resume <session-id> from CLI
Or a URL like claude.ai/code/session/<id> accessible from any browser
Session state (conversation history, project context) would be stored server-side and tied to the user's Anthropic account, similar to how claude.ai already saves conversations.
