feat(web-shell): add Session Overview panel and in-window split view (#6400)
* feat(web-shell): add Session Overview panel and in-window split view

Add a large-screen "Session Overview" mission-control panel and an
in-window split view so users can monitor and drive multiple daemon
sessions at once.

- SessionOverviewPanel: ranked live cards (needs-approval -> running ->
  idle) merging the workspace session list with the detail=full status
  report. Multi-select opens the selected sessions as a split view in
  the current tab ("Open in split") or in a new browser tab ("Open in
  new tab", via a ?split=a,b URL).
- SplitView + ChatPane: one DaemonWorkspaceProvider hosting N
  DaemonSessionProvider panes, each a self-contained interactive chat
  (transcript, composer, streaming, tool/ask approvals). Browser focus
  scopes the keyboard per pane, so panes never contend over approvals.
- Sidebar entry points gated to large screens; the split view's Back
  returns to the Session Overview.

* refactor(web-shell): address review feedback on the session overview / split view

- SessionOverviewPanel: prune the selection Set when a session leaves the list
  (so a reappearing session isn't silently reselected) and make select-all use
  the intersection rather than prev.size.
- Extract isAskUserPermission into a shared util so App.tsx and ChatPane.tsx no
  longer keep verbatim copies that can drift.
- SplitView: dismiss the "add session" picker on Escape or a click outside it.
- Tests: MAX_PANES cap, popup-blocked path, checkbox-selects-without-navigating,
  stale-selection pruning, and a direct test for the extracted util.

* fix(web-shell): address /review findings on the split view

- ToolApproval: add a `keyboardActive` prop; split panes pass false so global
  Enter/Escape/digit shortcuts can't confirm the wrong session's approval, and
  the outer session's approval overlay is no longer rendered behind the split
  (where it would keep its global shortcuts while hidden).
- ChatPane: defer the composer commit until sendPrompt resolves, so a rejected
  prompt (transcript loading / disconnected / turn active) preserves the draft
  instead of silently dropping it.
- SplitView: include a per-mount nonce in each pane's clientId so two tabs
  opening the same split don't share a client id — which suppressOwnUserEcho
  would treat as a self-echo and drop from the transcript.
- SessionOverviewPanel: cap the split selection to MAX_SPLIT_PANES before
  building the ?split= URL or opening the in-window split, with a hint when more
  are selected; also dismiss the split picker on Escape / click-outside.
- Tests covering each.

* fix(web-shell): address second /review round on the split view

- SplitView: wrap each pane in its own ErrorBoundary, so a render crash in one
  pane (malformed block, unexpected tool shape) shows an inline fallback with a
  close action instead of white-screening the whole split.
- splitUrl / overview: carry the daemon token into the new-tab split URL's
  fragment. The current tab has already stripped the token from its URL, so a
  token-auth (`serve --open`) deployment would otherwise open the split tab
  unauthenticated. The token rides the hash (never sent to the server / logs).
- Tests: per-pane error isolation, token-in-fragment (and none without a token),
  and the overview polling effects (interval fires, document.hidden skips, and
  the in-flight guard prevents overlapping polls).

* fix(web-shell): hide the outer chat under the split and share app-level contexts

- App: hide (display:none) + aria-hide the outer chat subtree whenever
  mainView !== 'chat', not only when a panel is open. Previously the outer
  chat/composer/toolbar stayed reachable by keyboard/AT behind the full-page
  split (it was only covered visually). State is preserved (node stays mounted).
- App: wrap SplitView in the app-level WebShellCustomizationProvider and
  CompactModeContext so split panes render markdown / tool-headers / thinking
  the same way the single-session chat does. Todo contexts stay chat-only —
  they belong to the outer session, not the panes.

* refactor(web-shell): address review suggestions — coverage, dedup, split UX

- ToolApproval: add a dedicated test on the real component that the global
  keyboard shortcut is armed by default and NOT armed when keyboardActive=false
  (the cross-pane approval safety mechanism).
- SplitView: auto-exit to the Session Overview when the last pane is closed
  (guarded so an initial empty seed doesn't bounce straight back out).
- ChatPane: add tests for the cancel action, the empty/whitespace submit guard,
  and error routing to the onError prop.
- Extract the shared session-list page size + organization feature flag into
  constants/sessions.ts, used by the overview, split view, and sidebar, so the
  values can't drift between the three.

* fix(web-shell): surface outer approval + failed refresh in overview/split

- Split view: when the outer (main) session is waiting on an approval
  that's hidden behind the split, show a non-blocking notice banner with
  a "Go to it" button that returns to the chat where the approval lives.
- Auto-close the split (like the overview panel) when the viewport shrinks
  below the large-screen breakpoint, so users aren't stranded.
- Session Overview: surface a failed refresh inline (keeping the last-good
  cards) instead of silently swallowing it once cards are on screen.
- Tests: status-report poll cadence, picker dismiss (Escape / outside /
  inside click), inline refresh-failure banner.

* fix(web-shell): sever window.opener on split tab; tighten hidden-chat test

- openSelectedInNewTab now clears win.opener (the split tab carries a
  daemon token in its URL fragment) to prevent reverse tabnabbing, matching
  the existing bug-report window.open path.
- Strengthen the split-view App test so a missing outer-chat subtree fails
  instead of passing vacuously through an optional chain.

* fix(web-shell): split-view focus/stability/robustness follow-ups

- Refocus the composer after a shrink-driven split close so keyboard users
  aren't dropped onto <body> (skips when an approval or panel takes over).
- Stabilize SplitView onExit via useCallback so its last-pane-close effect
  doesn't re-fire on every App re-render.
- ChatPane: surface a per-pane connection-loss banner instead of silently
  showing stale messages when a pane's daemon connection drops.
- ChatPane: anchor the streaming timer to the active turn's start (last user
  message timestamp) so a pane opened mid-turn shows real elapsed time.
- Tests: split auto-close on shrink, outer-approval split notice + return-to-
  chat, connection banner, and streaming-timer anchoring.
