What

Append a "Before opening a pull request" section to AGENTS.md so agents search existing PRs first and keep at most one open PR per task.

Why

Agents were opening parallel PRs for the same work (including fallback/review-policy drafts and renamed branches). This rule is the repo's agent instruction for that.

How was this tested?

• Listed open PRs (gh pr list --state open) and searched for an existing no-duplicate / AGENTS.md PR covering this task; none matched.
• Confirmed the appended markdown matches the requested rule text.
• No application code changed.

Checklist

• cargo fmt / clippy -D warnings / cargo test pass locally (N/A — docs-only)
• Protocol changes update both mb-protocol and docs/protocol.md (N/A)
• Adapter PRs: the adapter checklist is satisfied (N/A)
• Nothing added to the daemon's idle footprint (CPU, RSS, network)

• Trigger a manual review

To automatically review draft PRs, update your CodeRabbit configuration:
