No way to access previous session context or drag files into CLI

Feature Request

Two related issues that make session handover painful:

1. No access to previous session context

Each Claude Code session starts completely fresh with no way to reference prior conversations. The only persistence is files on disk and memory files, but if the previous session failed to save something (see #45557), that context is gone.

The user has no way to:

• Continue a previous session
• Reference what was discussed/decided
• Verify what the previous session claimed to do

This forces users to re-explain context every time, or copy-paste large blocks of conversation history.

2. No drag-and-drop support for files/images

The web version of Claude supports dragging files and images directly into the chat. Claude Code CLI does not. Users have to provide file paths manually or use workarounds.

This is especially painful when trying to share screenshots, PDFs, or reference documents mid-conversation.

Suggested improvements

• Allow resuming or referencing previous sessions (even read-only access to recent session transcripts)
• Support drag-and-drop of files/images into the CLI input (or at minimum, easy paste of images from clipboard)
• Better session handover: auto-generate a handover summary file at session end that the next session can read

Environment

• Claude Code CLI on macOS
