[BUG] Stop hook sends the wrong transcript_path

Environment

• Platform (select one):
• [X] Anthropic API
• Claude CLI version: 1.0.41
• Operating System: macOS 15.5
• Terminal: iTerm2

Bug Description

The "Stop" hook does not correctly update the transcript_path when the current session gets cleared using the /clear command

Steps to Reproduce

1. Create a "Stop" hook
2. Perform any claude prompt
3. Log the transcript_path that gets sent to the hook script
4. Clear the current session in Claude Code using /clear
5. Perform another prompt

Expected Behavior

The transcript_path points to a valid file that exists on the filesystem.

Actual Behavior

The transcript_path points to a non-existing file as the original session-id is still being used for writing to the transcript file.
