For people who run profiles as bots, the colored profile strip at the sidebar
foot duplicates the sessions list (community request). Add a persisted
`hermes.desktop.profileRailVisible` preference (on by default) toggled from the
Sessions view menu ("Profile rail"), the shell right-click menu, ⌘K
("Toggle profile rail") and an unbound `view.toggleProfileRail` keybind.
While the rail is hidden the statusbar grows a `ProfileSwitcher` dropdown
beside the gateway switcher ("This device ⌄ · Profiles ⌄") offering the same
choices the rail does: this gateway's profiles, All profiles, every other
gateway's agents in fleet mode, New / Import / Manage. It also answers the
`profile.create` hotkey the rail used to own, so no door is lost.
