keep the agent symlinks (#13968)
* Commit root AGENTS.md/CLAUDE.md symlinks so agents auto-load conventions
Track the root AGENTS.md/CLAUDE.md symlinks (-> .ai/AGENTS.md) instead of
generating them via `make claude`/`make codex`, so a fresh clone auto-loads
the agent guide with no setup step (matching transformers). The make targets
now only wire up skills; .ai/AGENTS.md, the contribution doc, and the PR
template are updated to match.

* Add documentation-impact check to PR review rules
During review, scan related usage docs and agent docs and flag (advisory)
any that should be updated based on the PR — outdated/missing usage docs, or
a rule/pattern/gotcha worth recording in the agent guides.
