[bug] oc_grep tool is causing builtin Grep tool to use grep over ripgrep

[exploitJ]

Description

I got this error while running opencode.

Now let me find the exact --grep occurrences in the plan file to fix them:
✱ Grep "--grep" in .sisyphus/plans/connector-manifest.md
Error: Command failed: grep -r -n --grep /path/to/project/plans/connector-manifest.md
grep: unrecognized option `--grep'
usage: grep [-abcdDEFGHhIiJLlMmnOopqRSsUVvwXxZz] [-A num] [-B num] [-C[num]]
	[-e pattern] [-f file] [--binary-files=value] [--color=when]
	[--context[=num]] [--directories=action] [--label] [--line-buffered]
	[--null] [pattern] [file ...]

In addition, I've seen many instances of failed Grep tool caused by mismatched parenthesies across many sessions.

OpenCode version

1.2.27

Operating System
