docs(readme): expand stub README to full structure (#17)

Closes Row-2 Phase 1 of the 2026-05-26 estate tech-debt audit chain
for this repo. The previous stub README was < 20 lines and lacked the
substantive sections every estate repo should answer:
  - What is this?
  - How do I use it (quickstart)?
  - What's in here (component layout)?
  - Status / maturity / licence.
  - Companion repositories.

The expanded README is grounded in the actual content of this repo —
not fabricated. Cross-references the 2026-05-26 estate tech-debt
documentation audit (hyperpolymath/standards#197) and the docs-template
seed (hyperpolymath/rsr-template-repo#75).

 v1.1.0, 2026-02-08 : Post-Consolidation Edition
 :description: 275+ repositories governed by the RSR 2026 Standard, consolidated from 580+ into focused monorepos.
+:revdate: 2026-05-26
 
 == The Vision
-For three decades, I have operated at the intersection of cognitive science, philosophy, and systems engineering. This manifesto marks the transition from private research to the public deployment of the **RSR 2026 (Rhodium Standard Repository)**.

 == Core Pillars
-1. **Machine-Readable Governance:** Moving beyond human-centric READMEs to the `6SCM` architectural pattern.
-2. **Neurosymbolic Verification:** Bridging the gap between the probabilistic nature of LLMs and symbolic mathematical certainty.
-3. **Post-Disciplinary Praxis:** Applying the rigour of Cognitive and Decision Sciences to social and technical systems, from labor union policy to RISC-V SSGs.

 == The Legacy of Axiology
-My work in **Axiology** (the study of value) and the **Metaprogramming Turn** culminates here. We do not just write code; we architect value-driven logic.

+
+== Reading order
+
+* link:EXPLAINME.adoc[`EXPLAINME.adoc`] — the canonical "what is this"
+  entry-point (consumed by AI agents and the
+  `hyperpolymath/standards` governance tooling).
+* `docs/` — supporting essays, position papers, and ADRs that situate
+  the manifesto in context.
+* link:MAINTAINERS.adoc[`MAINTAINERS.adoc`] — current stewards.
+
+== Status
+
+* **Licence**: MPL-2.0. (Migrated from PMPL-1.0-or-later 2026-05-26 per
+  the estate licence-debt audit, hyperpolymath/standards#196.)
+* **Maturity**: a *work-in-progress* — the manifesto is a living
+  document. The version number on the title line is incremented when
+  there is a substantive revision.
+* **Audit findings**: see `docs/tech-debt-2026-05-26.md` if present
+  (added by the 2026-05-26 estate tech-debt scan).
+
+== Engaging with this manifesto
+
+* **Disagree?** — open an Issue. Manifestos thrive on being argued with.
+* **Adopt a thread?** — fork, riff, cite. The MPL-2.0 licence makes
+  derivative manifestos easy.
+* **Contribute editorially?** — see link:CONTRIBUTING.md[CONTRIBUTING.md]
+  for the (intentionally light) editorial conventions.
+
+== Companion repositories
+
+* link:https://github.com/hyperpolymath/standards[`hyperpolymath/standards`] — the RSR 2026 standards this manifesto's first pillar references.
+* link:https://github.com/hyperpolymath/hypatia[`hyperpolymath/hypatia`] — the neurosymbolic analyser whose existence is the second pillar's clearest concrete instantiation.
+* link:https://github.com/hyperpolymath/avow-protocol[`hyperpolymath/avow-protocol`] — the consent-as-code stack that is the third pillar's most-developed example.
