Subject: [PATCH] fix(tui): add linear search fallback for session
 update/delete sync

Binary.search may fail to find sessions when the store array order
differs from expected sort order. This adds a linear search fallback
to ensure session updates (rename) and deletes are properly synced
to the UI.

Fixes #5494
Fixes #3779
