Oğuz YılmazandClaude Opus 5.5 54ec8c6584 feat: let operators keep the message subject out of the tab title
Opening a message puts its subject in the browser-tab title. The title does
not stay in the tab strip: browsers keep it in history and in the
session-restore list, and screen shares show it. For mailboxes that hold
other people's correspondence that is a leak nobody audits.

A new feature gate, tabTitleSubjectEnabled ("Subject in Tab Title" under
Admin -> Policy), is on by default, so nothing changes for existing
installs. With it off, the title names the folder instead, so the tab still
says where you are. It is an admin gate rather than a user setting: whose
mail the boxes hold is a deployment decision.

The gate counts as off until the policy has loaded, so a subject never
slips into history while the setting is still unknown.
