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

Steps:

Get the current session ID and project path: tail -1 ~/.claude/history.jsonl | jq -r '[.sessionId, .project] | @tsv'
Find half-clone-conversation.sh with bash: find ~/.claude -name "half-clone-conversation.sh" 2>/dev/null | sort -V | tail -1
- This finds the script whether installed via plugin or manual symlink
- Uses version sort to prefer the latest version if multiple exist
- The same script handles both half and quarter cloning; --quarter selects quarter mode
Preview the conversation to verify the session ID: <script-path> --preview <session-id> <project-path>
- Check that the first and last messages match the current conversation
Run the clone: <script-path> --quarter <session-id> <project-path>
- Always pass the project path from the history entry, not the current working directory
The script prints the new session ID (the New session: <id> line). Give the user the exact command to resume it directly, no picker needed:
```
claude --resume <new-session-id>
```
The script automatically appends a reference to the original conversation at the end of the cloned file. (The new session is also marked [QUARTER-CLONE <timestamp>], e.g. [QUARTER-CLONE Jan 7 14:30], so claude -r and picking it works as a fallback.)
