docs: record GRA-2456 productivity review

[Gradata]

Durable artifact for Paperclip productivity review GRA-2456.

Evidence recorded:

• Source issue GRA-135 remains todo and blocks GRA-130.
• Gradata/gradata-plugin is archived.
• PR feat: add codex-native plugin manifest + installer hook wiring gradata-plugin#11 is open, unmerged, and not mergeable.
• Recommended disposition: complete GRA-2456; move GRA-135 out of ordinary retry flow (prefer cancelled) and recreate active SDK/core work if still relevant.
