FABRIC-3.md: open new living document (bare metal boot); close FABRIC-2.md

FABRIC-2.md closed/archival as of 2026-09-04 -- its full punch list
(§I) was worked through to completion this session. FABRIC-3.md opens
as the new living document, topic: bare metal boot (FABRIC-2.md §I.6's
own Milestone 8, the one item that couldn't close from a coding
session -- needs a real machine and a human present).

First task written up before executing, per this series' own standing
discipline: merge v2.0.1 into master and verify build/function
equivalence on a clean master tree. Investigated the branch topology
first -- master is a strict ancestor of v2.0.1 (47 commits behind, no
divergent history), so this is a pure fast-forward, not a real merge.

Updated FABRIC-4.md's and .claude/CLAUDE.md's stale pointers at
FABRIC-2.md as "current/living" to point at FABRIC-3.md instead.
