* fix(mobile): use desktop's sort, colour, count and agent-row rules in the workspace list
Recent ignores terminal output, repo colours fall back to desktop's neutral,
Home counts skip archived rows, folder workspaces trail each lane, and a stale
agent row on a live terminal reads "No update in …" like desktop.
* fix(mobile): keep Delete disabled on a primary checkout, as desktop does
* fix(mobile): keep the task text on a silent agent row
* fix(mobile): show a silent agent row's time since its last update
* test(mobile): drop agent-row tests that replay the shared verdict
* refactor(mobile): check host PTY liveness once and keep the delete guard on the row flag
* test(mobile): re-record the home catalog goldens for the list's active count
