feat(rules): add F# review support - #1448

plugins/open-code-review/.cursor-plugin/plugin.json declares `skills` against an UNVERIFIED resolution base (manifest-dir). Cursor's plugin spec has not been checked against this repo. If Cursor resolves plugin.json paths from the plugin root (as Claude Code and Codex do), `../skills/` points at the non-existent `plugins/skills` and must become `./skills/`. Confirm against https://cursor.com/docs/plugins, then set base to the verified value and drop this field.
