SSE events not emitted when using `opencode attach --dir`

[tcrapts]

Description

When using opencode attach with the --dir flag to connect to a remote server, the server does not emit session.status SSE events when messages are sent/received. Without the --dir flag, events are emitted correctly.

Plugins

No response

OpenCode version

1.1.48

Steps to reproduce

1. Start OpenCode server: opencode serve --port 4096
2. In another terminal, listen to SSE events: curl -N "http://localhost:4096/event"
3. Attach WITH --dir: opencode attach http://localhost:4096 --session <session_id> --dir /path/to/project
4. Send a message in the attached terminal
5. Expected: SSE stream shows session.status events (busy → idle)
6. Actual: only heartbeat events are received, no session.status events

Workaround:
Attach WITHOUT the --dir flag - events are emitted correctly:
opencode attach http://localhost:4096 --session <session_id>
