[BUG] Hooks receive stale session_id and transcript_path after /exit and --continue

What's Wrong?

Environment:

• Claude Code version: 2.0.11
• Platform: Linux
• Hook type affected: All hooks (UserPromptSubmit, Stop, etc.)
• Trigger: /exit followed by claude --continue

When using /exit to close a session and then resuming with claude --continue, all hooks (UserPromptSubmit, Stop, etc.) continue to receive the original session's session_id and transcript_path instead of the current session's values. This persists across multiple exit/continue cycles, causing hooks to read conversations from hours/days ago instead of the current conversation.

Expected Behavior:

Hooks should receive the current session's session_id and transcript_path pointing to the actively-written transcript file.

Actual Behavior:

Hooks receive the first/original session's session_id and transcript_path from when the project directory was first opened, even though Claude Code is writing to a completely different transcript file.

What Should Happen?

When resuming a session with claude --continue, hooks should receive updated metadata:

• session_id: The current session's ID
• transcript_path: Path to the actively-written transcript file for the current session

Each exit/continue cycle should trigger hooks to receive fresh session metadata, not cached values from the initial session. Hooks should always point to the conversation currently being recorded, enabling real-time monitoring and context extraction from the correct transcript.

Steps to Reproduce

Steps to Reproduce:

1. Start a Claude Code session in a project directory
2. Set up a UserPromptSubmit hook that logs the received JSON (session_id and transcript_path)
3. Have a conversation, then use /exit to close
4. Resume with claude --continue
5. Send a new message
6. Check the hook's log

Related Issues:

Similar to #3019 (transcript_path after /clear) and #8614 (session ID with --dangerously-skip-permissions), but this affects normal exit/continue workflow.
