`GET .../wait` answers `blocked` at once for a codex pane showing a dialog,
because a screen-read dialog is a level the server is still reading. The
duplicate branch of `POST .../input` (a tagged retry after a dropped
connection, answered from current state) still used the plain
`currentSignalFor()`, so a retry with `wait: "blocked"` on a pane the first
delivery had already blocked waited out its whole timeout for an edge that
had passed. It now uses `currentSignalForWait()` like the GET route; a
caller that asked only for `idle` still gets `idle`.

http/Fastify servers in daemon-control, deepseek-status-shim, session-input-wait and the three tui tests listen on 0 and read address().port. The two "nothing listens here" ports (a fixed 3243, and the server's port + 1) come from closedPort(): bind 0, read the port, close.
