Release: fix Kanban column scrolling on mobile (#6306, @jpalazz2) (#6347)

* fix: Fix kanban scrolling in mobile viewports

Scrolling vertically (particularly in expanded view) in kanban on
a mobile viewport is difficult. The columns have overscroll
disabled, meaning tap and drag will only scroll within the column
and will not continue to the next section. On desktop it's much
easier to get the mouse outside the column div, on mobile you have
to deliberately try to tap very close to the edge of the viewport.

Disabling that behavior makes the experience much better

 ### Fixed
 
+- **Kanban board columns are now scrollable on mobile.** On a phone, a touch-drag inside a Kanban column was trapped in the column's nested scroller, so you couldn't scroll the board. The mobile layout now lets the column overscroll chain to the page/section, restoring natural scrolling; desktop and the pull-to-refresh behavior are unchanged. Thanks @jpalazz2. (#6306)
+
 - **Live Stream: Assistant Turn Anchors now carry a stable run identity through the settled scene.** The activity-scene projection now threads a stable `run_id` (independent of the transport `stream_id`) through Anchor scenes and client hydration, so a settled/reloaded Worklog keeps a consistent identity and can't mis-own or duplicate rows if a producer ever emits `run_id != stream_id`. Behavior-preserving for current writers (which still emit `run_id == stream_id`) — verified byte-identical live/settle/reload render, with malformed/conflicting identities falling back to the transport identity. Thanks @franksong2702. (#6201, #3400)
 
 - **Content search no longer evicts your open sessions from the cache.** A content search scans many sessions, and each scan used to promote/cold-load sessions into the in-memory LRU — evicting the sessions you actually have open. Search now reads through a scan-only accessor that keeps the same disk-freshness, journal-recovery, and state.db reconciliation (so recent content stays searchable) but doesn't disturb the working-set cache. Thanks @ai-ag2026. (#6084, #6083)
