Make the open session findable in the sidebar

[edgar965]

The open session was marked with a fill so faint it lost against New Session, which sat right above it as a filled button. The one that stood out was the one nobody was in.

Three changes to the same list:

• The open session carries an accent bar down its left edge plus a tint. New Session is a plain row that outlines on hover — starting a session is something reached for now and then, being in one is a state that has to answer at a glance.
• The recent-conversations list is marked the same way, so "which chat am I in" looks identical wherever it is asked.
• The list scrolls to the open session when it mounts. A window that opened on a conversation far down the list showed the top of it, and finding the current chat meant scrolling for it. block: 'nearest' leaves a row that is already visible where it is, so clicking between sessions does not jerk the list around.

The patch grows clear beneath the moon,
Small changes hop in place,
Tests guard the garden path,
Reviews bloom before the dawn.

Merge Risk: 🔵 Low · up to ad407

This PR strengthens active-session styling and brings the current session into view, but the selected recent-conversation title may still use normal weight rather than the stronger emphasis used for sessions, so the current chat can remain less scannable in that list. The issue is localized and mergeable with owner awareness or a small follow-up.

142-142: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Match the selected conversation text emphasis.

The selected project-session row applies font-medium when isSelected, but this recent-conversation title always uses font-normal. The selected conversation is therefore less distinguishable in the recent list.

Make the title class conditional on isSelected, while keeping font-normal for unselected rows.

Proposed fix

-                <span className="block truncate text-[13px] font-normal leading-4">
+                <span
+                  className={cn(
+                    'block truncate text-[13px] leading-4',
+                    isSelected ? 'font-medium' : 'font-normal',
+                  )}
+                >

so the later border-border/30 fallback is applied only when !isSelected,
preserving border-primary/30 whenever isSelected is true; keep the existing
non-selected styling unchanged.
