Ouroboros 35b8151819 Split the two reference books into verbatim chapters
The books were one physical file each: ARCHITECTURE 2,386 lines and
DEVELOPMENT 3,886, with 13 and 14 `##` sections. `reference_books.py` had
shipped the chaptered reader — membership, authored introductions, exact
physical source views — with the migration still at zero, so every reader
took the legacy monolith branch and the validator had no production caller.

Each `##` section is now one chapter file under `docs/architecture/` or
`docs/development/`. The only new bytes per chapter are its prologue: the old
section title at H1 (numbering text kept, so every `ARCHITECTURE "8. Git
Branching, CI, and Build"` cross-reference still reads) and one authored
introductory paragraph saying what the chapter owns and why it exists.
Everything after that prologue is the old section body byte for byte, with
`###`/`####` levels untouched — so the residue rules keep reading the exact
subsection headings they exempt, and no section title was renamed.

The move is therefore INVERTIBLE, and `tests/test_reference_book_migration.py`
inverts it: drop each chapter's H1 line and its one introduction, re-prefix
`## `, concatenate in membership order, and require the recorded SHA-256 of
the old body — plus, whenever the base commit is reachable, byte equality with
`git show <base>:<path>`. `docs/reference-books-migration.md` is the operator
transfer table: every row a verbatim move, with its line range at the base, its
destination and an empty rename column. It lives directly under `docs/`, so it
is reviewable without becoming a book member.

`_preamble` now takes the FIRST paragraph under the H1 instead of demanding the
only one before the first H2. Most sections open with prose at the level they
already had, so the old rule could only be satisfied by promoting `###` to `##`
or inventing a sub-heading — either of which would rewrite what this migration
relocates verbatim. A source whose H1 is followed straight by a subsection
still has no introduction and is still refused, which is the property that
keeps an overview from quoting body prose as authored orientation.

`.gitattributes` pins `docs/**/*.md` to LF: chapter line ranges, byte spans and
SHA-256s are physical facts that a Windows checkout must not rewrite, and
`full-test` runs on windows-latest for every PR. The two ARCHITECTURE-derived
generated inventories are regenerated, because a chaptered section now carries
its physical provenance note.

DEVELOPMENT.md — Development Principles & Module Guide

This is Ouroboros's engineering handbook: imperative rules for changing the body, grouped by change class, each naming the surface that enforces it — a test, a gate, a CI lane — or stating honestly that none does. The first chapter fixes this book's authority beside the constitution, the architecture map, the design semantics and the reviewer checklists; the rest are the rules themselves, from naming and size discipline through the governance-artifact contract, the commit protocol, the per-change-class rules, and the build and CI topology. Read the chapter for the class of change in hand: this book is not a changelog, and a change replaces the description of the node it touched.
