--- "aicodeman": patch --- Vertical tab rail: detailed rows, and a rename cancel that no longer wipes the name. The vertical rail (Tab Orientation → Vertical) now draws the same per-session line the home screen and the rich sidebar draw — when the session was created, how long it has been in the state it is in, the folder it runs in, and a status pill — instead of just the name. New per-device setting **Vertical Rail Rows** (`tabRailDetail`, App Settings → Appearance → Tabs) with `Detailed` as the default and `Simple (name only)` as the opt-out. A rail that has never been sized now opens at 320px (the existing Wide preset) so the line fits; a narrower rail sheds the created stamp below 288px and falls back to simple rows below 240px. Also fixes a data-loss bug in the inline tab rename that predates the rail: pressing Escape cleared the input and blurred it, and the blur handler commits — so cancelling a rename stored an EMPTY session name and the tab fell back to its folder label. Escape now cancels without a request, in every layout.
