feat: thread-safety hardening, launch docs, outreach drafts

Thread-safety: std.Thread.Mutex on all 9 FFI modules (55 globals,
~120 C-ABI exports), _impl pattern for deadlock prevention,
2 concurrent seam tests (307 total). panic-attack validated:
1 weak point (QUIC crypto, expected), 0 critical.

Docs: wiki (5 pages), operator quickstart, getting started,
extensibility guide, architecture thread-safety section,
changelog populated, test counts fixed to 307.

Outreach: arXiv paper draft, IETF Internet-Draft outline,
Show HN post, dev.to blog post, 6 awesome list descriptions.

Security: fixed security.txt double-prefix and TODO field.

 == Project Status
 
-10 components at Grade D (Alpha): all ABI+FFI layers type-check and pass unit tests. 7 components at Grade X (stub/spec only). See `READINESS.md` for the full CRG assessment and `.machine_readable/STATE.a2ml` for milestone progress.
+**Grade A (Production)** — 18 cartridges, 307 tests passing, thread-safe FFI (mutex-hardened), panic-attack validated.  See `READINESS.md` for the full CRG assessment and `.machine_readable/STATE.a2ml` for milestone progress.
+
+== A Community Project
+
+This is a community project. Nobody makes money from it. It exists because the problem (too many servers, too much fragmentation) needed solving, and the solution needed building.
+
+**What would help most right now:**
+
+* **Host a node** — Even for a few hours a week. Pull the container, let it gossip. Every node strengthens the network. See `docs/OPERATOR-QUICKSTART.md`.
+* **Try it out** — Use it via MCP, REST, or gRPC. Break things. Tell me what's confusing, what's missing, what doesn't work.
+* **Build on it** — Write a cartridge, create an extension, wire it to your own tools. The third axis is wide open.
+* **Give feedback** — Comments, issues, PRs, emails, carrier pigeons. All welcome.
+
+A huge thank you to anyone who takes the time to look at this. Even a quick glance and an honest opinion helps enormously. I built this to learn from it, and I learn most from other people using it.
