Note

Low Risk
Documentation-only changes to Code Review configuration guidance with no runtime or security impact.

Overview
Updates the Exclude scans section in code-review/config.mdx to match current bot and skip-check behavior.

The intro now states that excluded matches still record a skipped check with no seat use, and that on GitHub, excluded bot PRs do not get a skip comment (the previous wording about a comment naming the rule was removed).

A new Note explains when GitHub bot PRs are auto-reviewed (same-repo source branch only), that fork bots and outside human contributors are not auto-scanned, how GitLab/Bitbucket bots relate to normal coverage and seats, that eligible bots can consume a Code Review seat when auto-assignment is on, and how to opt out via exclude.authors.
