Bohdan Triapitsyn 85400459e9 perf: overhaul session loading, caching, and runtime isolation (#2360)
Improve OpenChamber responsiveness under large session workloads while fixing
cache, synchronization, and persistence correctness across runtimes, projects,
directories, and worktrees.

- prioritize selected and visible sessions during bootstrap and defer
  non-critical enrichment work
- reduce redundant message loading, event processing, store publication, and
  hidden sidebar work
- prevent stale session and message requests from overwriting newer
  authoritative state
- preserve existing data when authoritative fetches fail instead of treating
  failures as successful empty responses
- scope session materialization, messages, drafts, queues, todos, pins,
  permissions, folders, tabs, Git state, and pull request data by runtime and
  directory identity
- harden runtime switching, reconnect, cleanup, mutation reconciliation, and
  persisted-state ordering
- preserve live subagent Task linkage when metadata arrives after an older
  message request or while streaming parts are suspended
- coalesce overlapping tail refreshes without losing newer refresh demand
- improve cold-session loading by moving deferrable work out of the critical
  bootstrap path
- isolate URL authentication, mobile credentials, native secrets, and other
  runtime-owned state across endpoint changes
- bound long-lived caches and remove avoidable allocations from event and
  rendering hot paths
- limit virtualization to archive collections where it improves rendering
  without disrupting active sidebar layout
- stabilize session folders, pin ordering, expanded state, and persisted
  sidebar behavior
- open skill files through the same secure editor and outside-workspace grant
  flow used by file navigation, including worktree sessions
- expand regression coverage for stale completions, runtime collisions,
  reconnect behavior, persistence races, authoritative empty results, and
  subagent refresh ordering
- document the updated synchronization, cache ownership, performance, and
  runtime-isolation invariants

Tom RochetteandBohdan Triapitsyn e8be7ef55b fix(mobile): eliminate >10s sidebar open delay by always mounting SessionSidebar (#1695) (#1738)
* fix(mobile): always mount SessionSidebar to eliminate >10s drawer open delay (#1695)

On mobile (Android PWA), SessionSidebar was conditionally mounted via
{mobileLeftDrawerVisible && ...}, causing the component to unmount on
drawer close and remount on every open. Each remount fired a full
data-loading cascade: paginated sessions fetch (PAGE_SIZE=500 with
retry), worktree discovery, repo status, PR status, 10+ useMemo
recomputations, and localStorage reads, manifesting as a >10s delay
before the drawer became interactive.

Desktop already avoided this by keeping SessionSidebar always mounted
inside <Sidebar> with a CSS visibility toggle.

Fix: remove the mobileLeftDrawerVisible conditional wrapper so
SessionSidebar stays mounted on mobile too, matching desktop behavior.
Visibility remains controlled by the leftDrawerX transform (off-screen
when closed). Added pointer-events-none when hidden as a defensive guard.

Added a regression test that fails if the conditional mount pattern is
reintroduced around the mobile SessionSidebar.

* fix(mobile): hide closed drawer to avoid rotation offset leak
