Scrim now uses pointer-events-none — it dims visually but clicks pass
through to the cards beneath. Dismissal relies on onMouseLeave on the
wrapper div, which fires when the mouse leaves the card area.

The fixed scrim was catching the mouse, keeping the hover alive
indefinitely. Now the scrim has onMouseEnter={() => setIsHovered(false)}
so moving the mouse anywhere off the expanded card dismisses it.

On hover, the card:
- Grows slightly wider and floats directly over the base card
- Shows detail content (tried, result, reason, steps)
- Dims everything behind it with a fixed black/30 scrim
- Heavy drop shadow for depth (0 8px 32px rgba(0,0,0,0.5))
- Status-colored border maintained
Active branch still shows detail inline (no hover needed).
Cards below don't shift — the expanded version is position: absolute.

- Active branch: detail shows inline below the card header (no push)
- Hovered non-active: detail appears as a floating popover to the
RIGHT of the card (position: absolute, z-50, left-full)
- Popover has shadow, status-colored border, fade+zoom entrance
- Cards no longer shift or push siblings on hover
- Extracted BranchDetail component shared by both inline and popover

- Sidebar: click-and-drag resize handle (200-500px range), accent
highlight on drag, cursor changes to col-resize
- BranchNode: hover/active expands to show context_summary (tried,
result), status_reason, and step count with smooth animation
- ForkCard: "Fork Point" label changed from text-muted to
text-accent-text for visibility against bg-card

BranchNode renders a branch button with depth-based indent, status icon,
and status badge using the design system color palette. BranchMap builds
a tree from the flat branch list via buildTree/flattenTree and renders
all nodes with a GitBranch header.
