The Daytona SDK's process.exec(timeout=N) parameter is not enforced — the server-side timeout never fires and the SDK has no client-side fallback, causing commands to hang indefinitely. Fix: wrap commands with timeout N sh -c '...' (coreutils) which reliably kills the process and returns exit code 124. Added shlex.quote for proper shell escaping and a secondary deadline (timeout + 10s) that force-stops the sandbox if the shell timeout somehow fails. Signed-off-by: rovle <lovre.pesut@gmail.com>
