Grok Build 1.0.5 sharpens agent workflows

This is a practical infrastructure update that matters more to power users than headline features.

• –`GROK_CONFIG` and `GROK_CONFIG_PATH` let teams customize launches without mutating shared `config.toml` files.
• –Worktree handling strengthens Grok Build’s appeal for parallel agents and isolated development tasks.
• –The changes make integrations with editors such as Cursor more plausible and less brittle.
• –Frequent releases suggest xAI is iterating aggressively while the product is still maturing.
• –Because Grok Build can execute shell commands and modify repositories, teams should validate configuration precedence and permissions in sandboxed environments.
