/add feature to do full code review based on folder, not on latest git commit

[Constey]

Hi there,
i would like a full code review regarding quality, security, performance and so on on my full codebase. But it seems either /review or  /codex:adversarial-review fails on my environment always since it tries to keep on the git diff, and sometimes the git diff is very large so it runs in a buffer overflow. It should take just the currentl folder and make a fully research instead of checking in which worktree or branch we are workin on?

Kind regards,
Constey
