The dashboard's tab strip now runs on the shared createTabStrip
(@hive/shared/tabs.js) — the third and final consumer of #1464 step 1
(after logs + the agent window selector).
- activateTab is reduced to the per-tab side-effects only
(body.dataset.activeTab, the selection-bar gate, the lazy-loads);
createTabStrip owns the active tab/pane toggle + aria-selected + hash
routing, calling activateTab via onShow. Panes switch via the `hidden`
attribute (was a `.tab-pane-active` class) — the markup carries `hidden`
so there's no flash before the script runs.
- the responsive overflow menu is DROPPED per the design call (move panes
to their own pages rather than hide them in a dropdown). Removes ~150
lines: updateTabbarOverflow, closeOverflowMenu, the click/keydown
handlers, the ResizeObserver + MutationObserver, and syncTabFromHash.
S3TT1NGS is a regular strip tab now (no data-overflow).
- CSS: .tab.active becomes .tab.hive-tab--active; pane visibility is now
.tab-pane[hidden] { display: none }; the overflow dropdown styles are
gone. Count pills (setTabCount/refreshTabCounts) are unchanged.
Behaviour-preserving except the deliberate overflow removal; aria-selected
is now standardised on the tabs.
