feat(hub-ui): reopen a group's last-opened member ahead of defaultChildId

[antfubot]

What

Group docks now remember the member last opened in them, per tab. Activating a group reopens that member directly — taking precedence over the group's defaultChildId — instead of showing the member popover again.

For a group A with members B C D and no defaultChildId: the first click on A reveals the member popover; picking D opens it and records it. Toggling A closes the panel, and the next click reopens D straight away. When a defaultChildId is set, it seeds the first activation and the last-opened member wins from then on.

How

• DockSessionStorage gains groupLastChildIds (group id → member id), persisted beside selectedDockId/recentDockId in the per-tab devframes-dock-session store, so the memory survives reloads without two tabs fighting over it.
• switchEntry records every grouped-member selection (popover, group sidebar, command palette, RPC activation all funnel through it) and resolves a group activation through the new resolveGroupPreferredChild — last-opened member first, then defaultChildId, each under the existing when/visibility rules, then the first member.
• The dock-bar group button uses the same resolution before falling back to the popover.
• A remembered member that no longer resolves (removed, or its when clause fails) falls back to defaultChildId gracefully.

Covered by new unit tests for resolveGroupPreferredChild and a createDocksContext round-trip test; docs and story descriptions updated.
