Grok Build 0.2.58 changelog - what changed

[new] --background-wait-timeout flag sets the maximum seconds to wait for background work (bash/monitor tasks, background subagents) after the first turn ends in headless mode.
[new] --no-wait-for-background flag exits immediately after the first agent turn without waiting for pending background work (headless only).
[changed] All shell completions (bash, zsh, fish, elvish, powershell) now include the two new flags with their descriptions.
[changed] Background tasks user guide updated to document the revised get_command_or_subagent_output usage (timeout_ms only; removed block=true form).
[changed] Bundled model configuration examples now use a 256k context window.
