fix(install): pass action arguments through installer chain

Fixed argument passing in install_tool.sh and dedicated_script.sh:
- install_tool.sh now passes all arguments after TOOL_NAME to the installer
- dedicated_script.sh removes TOOL argument before passing to dedicated script
- Dedicated scripts (install_uv.sh, install_rust.sh, etc.) expect ACTION as $1

This fixes guide.sh calling "install_tool.sh uv reconcile" which was
previously failing with "Usage: install_uv.sh {install|update|uninstall|reconcile}"

Argument flow:
  guide.sh → install_tool.sh uv reconcile
           → dedicated_script.sh uv reconcile
           → install_uv.sh reconcile ✓
