Enhanced Session Persistence

What: Complete rewrite of session persistence system to support remote server synchronization How to use:

# Session data now automatically syncs with remote servers when available
# Uses CLAUDE_CODE_WEBSOCKET_AUTH_FILE_DESCRIPTOR for authentication
export CLAUDE_CODE_WEBSOCKET_AUTH_FILE_DESCRIPTOR=3
claude --session-id my-session

Details:

• Sessions can now be persisted to and restored from remote servers
• Cross-platform file descriptor support (Darwin/FreeBSD use /dev/fd/, Linux uses /proc/self/fd/)
• Automatic conflict detection and resolution for concurrent session modifications
• Improved error handling with detailed logging for session operations
