fix(cli): ag run streaming output hangs — wrong response field names (#3368)

The read endpoint (/v1/sessions/:id/read) returns { messages, status },
not { lines/transcript, status }. The CLI was looking for non-existent
fields, so it never received any entries and the stream appeared to hang.

Also:
- Skip non-text content types (thinking, tool_use, tool_result) in output
- Added 'crashed' to terminal status detection
- Show statusText when available for better end-of-session messages

Fixes: #3368
