Feature request: Cross-device session sync / resume

Feature Request

I use Claude Code on multiple Macs and want to resume sessions started on one machine from another. Currently, session data (JSONL in ~/.claude/projects/) is stored locally and tied to absolute paths.

Proposed solution

• Cloud-based session storage (opt-in) for claude --resume from any device
• Or claude session export/import command with portable path resolution

Why it's hard today

• JSONL files embed absolute cwd paths
• Project dirs under ~/.claude/projects/ are named from absolute paths
• Manual sync via Syncthing/rsync is fragile
