Clone the later half of the current conversation, discarding earlier context to reduce token usage while preserving recent work.

Steps:
1. Get the current session ID and project path: `tail -1 ~/.claude/history.jsonl | jq -r '[.sessionId, .project] | @tsv'`
2. The script is bundled at `scripts/half-clone-conversation.sh`
3. Preview the conversation to verify the session ID: `scripts/half-clone-conversation.sh --preview <session-id> <project-path>`
   - Check that the first and last messages match the current conversation
4. Run the clone: `scripts/half-clone-conversation.sh <session-id> <project-path>`
   - Always pass the project path from the history entry, not the current working directory
5. Tell the user they can access the half-cloned conversation with `claude -r` and look for the one marked `[HALF-CLONE <timestamp>]` (e.g., `[HALF-CLONE Jan 7 14:30]`). The script automatically appends a reference to the original conversation at the end of the cloned file.
