release v4.0.0-alpha.1: accepted in full, logs and record [skip ci]

The acceptance protocol on b7534107 (LithosAnanke v4.0.0-alpha.1), in this
session, one QEMU at a time in the foreground:
- amd64 logs/20261107-150809, aarch64 -151023, riscv64 -151359: [zuse@Hera]
  ok>, PARITY:V4_POST tests=538 pass=538 fail=0, POST: PASSED,
  dict_hash=0xfec8c47cfc6f437f on all three
- the PC stick loaded high, logs/20261107-151539: the same, no fault
- make -C v4 test-32: 39 programs, 0 failures
- Isabelle/HOL proofs, logs/20261107-152312/isabelle: Finished StarForth

CHANGELOG and FABRIC-3.md XLVII: the ruling, what was verified, and what
an alpha leaves open (the v4.0.0 milestone; unsigned capsules until the
StarshipOS CA).

 # Changelog
 
+## 2026-11-07 — LithosAnanke v4.0.0-alpha.1: the first alpha release
+
+The first alpha of the kernel, `v4.0.0-alpha.1`: v4, StarForth's F18 engine, is the system every
+board boots by default, with v3 a boot argument away. The kernel's version goes from 2.1.0 to the
+4.x working line (Captain Bob, 2026-11-07); the engine stays 3.2.0. Accepted in full before the tag:
+amd64, aarch64 and riscv64 to `[zuse@Hera] ok>` with POST 538/538 and one `dict_hash`
+(`0xfec8c47cfc6f437f`), the PC stick loaded high, `test-32` (39 programs, 0 failures), and the
+Isabelle/HOL proofs. An alpha: the v4.0.0 milestone's own definition -- parity with v3's vocabulary,
+K=1.0 measured on v4, the hosted mesh, Verilator -- is still open, and the capsules are unsigned until
+the StarshipOS CA is made (FABRIC-3.md XLVI). Also today: CI in a prebuilt runner image, the
+nightly's proofs no longer able to hold back its images, and the .com and .org websites. Full record:
+`docs/fabric/FABRIC-3.md` XLVII.
