Session name reverts after context compaction

Description

After renaming a session with /rename, the session name appears to revert/change after context compaction occurs. The custom name gets overwritten, likely by the auto-generated title logic re-triggering during compaction.

Steps to reproduce

1. Start a new Claude Code session
2. Rename it with /rename to a custom name
3. Continue working until context compaction is triggered (long conversation)
4. Observe that the session name has changed back to an auto-generated name

Expected behavior

The session name set via /rename should persist across context compaction events.

Actual behavior

The session name changes/reverts after compaction, suggesting the auto-title generation runs again during or after compaction and overwrites the user-assigned name.

Environment

• Claude Code on Windows 11
• Observed across multiple sessions
