Grok Build 0.2.56

• [new] grok sessions delete <id> command now lets you permanently remove a session from the CLI.
• [new] resume_from now continues a finished sub-agent in place instead of forking a new conversation.
• [fix] resume_from now correctly continues a sub-agent in the same working directory it was using before.
• [fix] Sandbox profile is now preserved when resuming sessions so commands continue to work as before.
• [fix] MCP server connections no longer get torn down during rapid config reloads.
• [fix] Stale leader processes are now cleaned up when leader mode is disabled via config or remote settings.
• [fix] list_dir now shows more relevant files when a large directory appears early in alphabetical order.
• [fix] list_dir now gives clearer guidance when a directory is too large, using the actual tool names available in your session.
• [fix] Cancel button in turn status always shows [stop]; queue pane highlight now follows theme changes.
• [fix] grok quit no longer hangs when background git or network tasks are slow.
• [fix] The token count shown after auto-compaction now matches the context bar exactly.
• [fix] The git branch icon now renders correctly in iTerm2 without a Nerd Font.
• [fix] Ctrl+Enter now sends the prompt when the agent is idle (same behavior as Enter).
• [fix] Files with non-ASCII names (e.g. Chinese) no longer crash the session when plan mode checks for markdown.
• [fix] Session lists (welcome screen, /resume, grok sessions list) are now sorted by the same activity time shown in the UI.
• [fix] Fixed bash tool failures when models send numeric arguments such as timeout as JSON strings instead of numbers.
• [fix] Prevented crashes during bash command output streaming when building progress frames.
• [fix] Disabled inline image rendering on iTerm2 terminals where scrollback overlays cannot be supported.
• [changed] Fast tools like grep now show as completed immediately even when other tools in the same round are still running.
• [changed] Long sessions that display inline images no longer grow to multi-GB memory usage.

Under the hood

• Shell completion scripts updated for the new sessions delete subcommand across bash, zsh, fish, elvish, and PowerShell.
• Documentation clarified for Ctrl+Enter behavior when idle, sandbox profile handling on resume, and permission lock enforcement details.
• Internal skill help references and bundled manifest checksums updated.
