* perf(mobile): slow certified terminal inventory sweeps
* fix(mobile): recover terminal inventory after stream teardown
* fix(mobile): keep fast sweeps while tabs drop a connected terminal
Tab snapshots are partial and only ever add terminals, so `terminal.list`
is the sole remover. With healthy sweeps slowed to 1/min, a background
terminal closed on the desktop lingered up to 60s, leaking its WebView and
leaving tabStripVisible stale.
Carry `connected`/`orphaned` through TerminalRecord and treat absence of a
connected, non-orphaned handle as a hint to schedule the authority -- never
as a decision to prune. Parked leaves and orphaned PTYs are legitimately
untabbed forever, so excluding them keeps the slow cadence from pinning.
