Add Unwrap() to StatusWriter so http.ResponseController.SetWriteDeadline
can reach the underlying net.Conn through the middleware wrapper. Without
this, the agent's 20s WriteTimeout killed blocking process output
connections.
Also add 30s headroom to the write deadline in handleProcessOutput so
the response can be written after a full-duration blocking wait.
On the tool layer, waitForProcess and the process_output tool now try a
non-blocking snapshot on any error, not just context timeout. Transport
errors (like the WriteTimeout EOF) previously returned with no process
ID and no recovery path. Now if the process finished, the result is
returned transparently. If still running, the error includes the process
ID and tells the agent to use process_output.
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
