Desktop Code tab: Session Rail can't be resized, so the Changes card truncates PR titles and hides PR numbers

Problem

In the Code tab, the Session Rail has a Changes card. It lists each PR with its title, repo, PR number, diff stats and checks status.

The rail is narrow and fixed-width. The only control is show or hide, so it can't be resized.

• A row with diff stats and a checks count (+61 −23, 13/14) cuts the PR number off.
• A row without stats shows the number but still truncates the title.

Why it matters

Ticket IDs and PR numbers are how I tell what's in flight. Before the redesign, PRs sat in a wide row above the prompt box, and the full title and number were readable. For anyone running several PRs, this is a regression.

Tried

Dragging the rail's edge does nothing. Panels can be rearranged but not resized.

Expected

Any of these would fix it:

• a resizable Session Rail
• the PR number always shown before the truncated title
• a two-line title mode
• an option to restore the wide row above the prompt
