Subject: [PATCH] fix: clean up hook event labels in Activity panel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace raw SDK identifiers with human-friendly labels (e.g.
sessionStart → Session start) and drop the meaningless UUID detail.
Labels now read like 'Session start hook started' instead of
'Hook sessionStart started'.
