cache the kernel ref so dispose() can actually clean up (T-366)

Browse Source 
ClideKernel.of(context) is an illegal ancestor lookup inside
dispose(); both panes wrapped it in catch (_) and silently did
nothing. The terminal pane therefore never sent pane.close (backend
PTY + daemon pane leaked per closed pane) and the Claude pane never
removed its settings listener. Both now cache KernelServices in
didChangeDependencies and the swallow-everything helpers are gone.
New terminal_pane_test covers the close-on-dispose path; note in it
why the whole tree must unmount (harness Overlay keeps
initialEntries across rebuilds).
