kaish-kernel 0.8.1

//! Kernel-routed integration tests for the `git` builtin.
//!
//! The builtin now lives in the `kaish-tools-git` crate and runs against the
//! portable `ToolCtx` surface; these drive it through the full kernel dispatch
//! (registration → ToolCtx → GitVfs over a real `LocalFs` worktree), which is
//! exactly the path that matters now that the tool is out-of-tree. Requires the
//! `git` capability.
