Address correctness and residual jank found in review:
- Expand pane session equality for connect/startup fields (pendingInitialCwd,
startupCommand, pending scripts, serial/local shell, etc.).
- Cache coding-CLI provider in the signal controller so memo-skipped
TerminalLayer renders cannot clear titles via a stale sessionsRef.
- Heal terminalCwdStore drift when the renderer ref already has the path.
- Publish shell history synchronously on write/load and via useLayoutEffect.
- Move script runs to scriptRunsStore; Scripts slot subscribes so automation
ticks no longer re-render TerminalLayerInner.
- TerminalLayerView equal uses stable side-panel keys only (cwd/theme live
via sidePanelLiveStore, not chrome re-renders).
- Compare terminalFontFamilyId / session log props; stabilize HostTreeView
callbacks and end-session-drag handler.
