The workspace terminal died everywhere: bun's node:http client never
emits the client 'upgrade' event (it surfaces the 101 as a plain
response), so docker-modem's exec.start({hijack:true}) waited forever —
a connected WebSocket with no bytes flowing (prod), or an instant close
when the socket was unreachable (dev). The pre-Phase-1 bridge avoided
dockerode attach for exactly this reason; the real-TTY-resize rewrite
reintroduced it.
- runtime/exec-stream.ts: speak the exec-start HTTP upgrade over a raw
net socket (docker and podman both answer 101 UPGRADED). Works under
bun and node; honors the modem's socketPath/host:port. The stream is
returned paused so the first screen paint can't race the caller's
data handler. Exec create/resize stay on dockerode (plain POSTs).
- user-container.ts: acquireUserBox re-ensures the container on every
acquire instead of trusting a cached "initialized" flag, so a box
removed behind the worker's back (manual rm, another instance's
reaper) is recreated instead of bricking terminals and agent turns
until restart.
- terminal.ts: bridge failures are logged and close the WebSocket with
a clamped human-readable reason instead of a silent catch;
xterm-session.tsx displays that reason instead of a mute
"Session ended". Also roomier terminal line spacing (1.2 -> 1.35).
