react-best-practices: AGENTS.md references ./<rule>.md files that live under rules/, and rules/area-description.md does not exist

Found while vendoring this skill verbatim (pinned at 7c180d9044c9ae2b442b567aad4e42a28dd5ed62) into a downstream content catalog that preserves upstream relative paths byte-for-byte.

Issue 1 — dangling sibling references in AGENTS.md: AGENTS.md links sibling rule files with relative paths like ./async-defer-await.md and ./server-hoist-static-io.md, implying they live alongside AGENTS.md. They actually live under rules/ (e.g. rules/async-defer-await.md), so the links as written do not resolve relative to AGENTS.md's own location.

Issue 2 — missing file referenced from README.md: README.md references rules/area-description.md, which does not exist in the repository at the pinned ref.

Both were found purely by resolving the literal relative paths against the on-disk tree — no assumptions about install-time transforms. Flagging in case these are meant to resolve for direct repo readers as well as tooling that flattens/installs the skill.
