docs: sync HONEST_DISCLOSURE.md from GitHub main (retired-organs notice) — restore byte-identical

Manual mirror: hf-sync.yml only mirrors README + front-door HTML/JS, not this doc. Adds the factual retired-organs notice already canonical on GitHub main. Honesty-preserving, never overclaims.

 # HONEST_DISCLOSURE — a11oy Receipt Signing
 
+<!-- RETIRED-ORGANS-NOTICE -->
+> **⚠️ Retired organs notice.** `amaru`, `sentra`, and `rosie` have been retired and consolidated into the **[a11oy](https://github.com/szl-holdings/a11oy)** flagship (Memory, Sentinel, and Operator verticals). Their standalone `szl-holdings/{amaru,sentra,rosie}` GitHub repositories and `szlholdings-{amaru,sentra,rosie}.hf.space` Hugging Face Spaces **no longer exist**; only the signed GHCR images persist, for supply-chain verification. Any amaru/sentra/rosie Space URLs, repo links, or endpoints referenced below are **historical and not live** — use a11oy instead.
