Bash tool's built-in prompt no longer varies its git-hooks guidance based on available tools

What

The instructions built into Claude Code's Bash tool (and its PowerShell equivalent) no longer receive a per-call list of dynamic tools. Previously the prompt included a conditional bullet about git hooks that depended on which tools were available; that has been replaced with a single, unconditional "For git commands" section shown every time.

Why

This simplifies the Bash tool's instructions so the git-hooks guidance is always present rather than appearing or disappearing depending on context, making the behavior more predictable.
