Describe the enhancement you want to request

Hi,

I want to use a ripgrep configuration to influence the tools grep and glob since they are using ripgrep as documented. However, ripgrep configurations are used by other tools like vscode, too. Therefore I need a way to specify a custom opencode ripgrep configuration file.

This would have a nice effect on permissions for grep and glob since read permissions do not influence grep permissions. AFAIK ripgrep ignore files or config files are the only way to deny reading access by ripgrep on a file based approach.

It would be nice if the custom path can be configured relative to the workspace.

Thank you for your time 😊!
