chore(rename): vext → vcs-ircd; add disambiguation manifest and README notice

Repo renamed on GitHub to hyperpolymath/vcs-ircd to avoid collision with
the Vext cryptographic verification protocol in burble/. Added:
- 0-AI-MANIFEST.a2ml: full disambiguation with box diagrams for bots/people
- README.adoc: WARNING admonition block at top redirecting wrong arrivals

+====
+*Name disambiguation* — two things were called "vext". They are unrelated.
+
+* *You are here:* `vcs-ircd` (formerly `vext`) — a *pooled IRC notification daemon* for
+  VCS events (Git push, commit, PR). Rust/Tokio. Nothing to do with cryptography.
+* *Not here:* the *Vext verification protocol* in Burble — BLAKE3 hash-chain feed
+  integrity for voice/chat. Lives at
+  `burble/server/lib/burble/verification/vext.ex`.
+
+If you want the verification protocol → go to the `burble` repo. +
+If you want to send Git commit notifications to IRC → you are in the right place.
