Add extensible remote session backends, safe ownership and restore handling, and pane-scoped shell integration over the existing SSH connection.
Keep iOS workspaces in memory and rebuild expired Activity targets on demand. Integrate session selection into Connection Journey with consistent controls, cancellation behavior, and localized counts.
Move connection policy out of ProAccess, keep terminal uploads with their
session, and share question interaction and highlight editing operations.
Consolidate CPU usage and settings snapshot handling, and remove obsolete
terminal selection, theme helpers, and hard-coded latest-schema assertions.
Fix draining connection-pool recovery and stale pane upload bindings. Keep
screenshot matrices opt-in and retain behavioral migration coverage.
Validation: 2468 macOS tests passed serially, 31 iOS tests passed, and both
SSH forwarding regressions passed against the local OpenSSH fixture.
Both app builds, Swift formatting, AppStrings, and Chinese localization
checks passed. Parallel test runs still exhibit intermittent timeouts.
