docs(readme): expand stub README to full structure (#72)
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).

`my-lang` is the *next-generation language* working project — a
13+
multi-dialect surface for the hyperpolymath language stack. It is one
14+
of two flagship language experiments in the estate (the other being
15+
link:https://github.com/hyperpolymath/affinescript[`affinescript`]).

[NOTE]
188-
====
189-
"Complete" for the Solo dialect means the *language machinery* — lexer, parser,
190-
type checker, tree-walking interpreter, and REPL — is feature-complete and can
191-
run arbitrary Solo programs.
192-
193-
It does *not* mean the *runtime standard library* is finished. The stdlib is
194-
delivered as native builtins and is being filled in under Phase 2 (file I/O,
195-
`env_args`, `format`, and string-keyed maps have landed; JSON and date
196-
primitives are next). Live status is tracked in the GitHub issues, not in this
197-
table — see the Phase-2 stdlib tracker (`#45`) and its sub-issues.

* **Licence**: MPL-2.0. (Migrated from PMPL-1.0-or-later 2026-05-26 per
67+
the estate licence-debt audit, hyperpolymath/standards#196.)
68+
* **Maturity**: design-iteration. Working compiler exists; surface and
69+
semantics still settling. Per the maintainer's memory entry
70+
`my-lang-37-shipped-rest-parked`, item #37 has shipped and several
71+
follow-ups (`#38-#41`) are artefact-blocked.
72+
* **Audit findings**: see `docs/tech-debt-2026-05-26.md` if present
73+
(added by the 2026-05-26 estate tech-debt scan).
