The lineage commit associations panel surfaced low-value provenance
metadata. Remove the UI section, its dead state/fetch wiring in
TaskChangesTab, the orphaned .task-lineage-* CSS, and the obsolete
tests. The fetchTaskCommitAssociations API helper is retained.
- Broaden mobile media query to include (max-height: 480px) so landscape
phones (which exceed 768 CSS px wide) still render the bottom nav and
mobile board layout instead of desktop horizontally-scrollable columns.
- Guard useMobileKeyboard against pinch-zoom (vv.scale > 1) — Android
Chrome ignores user-scalable=no, and a focused textarea + zoom was
false-positiving keyboard-open and hiding MobileNavBar.
- Read documentElement.clientHeight instead of stale window.innerHeight
when computing keyboard overlap (Android multi-window can leave
innerHeight cached at a wildly different value than the actual layout
viewport — observed 2848 while html was 797).
- Add interactive-widget=resizes-content to the viewport meta so Android
Chrome shrinks the layout viewport with the soft keyboard, matching iOS.

Adds task lineage commit associations: a new API route stores and exposes which commits belong to which task, the `TaskChangesTab` surfaces these lineage links visually, and documentation covers the reconciliation model. Includes comprehensive tests for both the route and component.
