Claude 16b9747d33 chore(license): the source headers name the Starship License 1.0 (SL-1.0), as LICENSE does [skip ci]
347 headers said "Licensed under the StarForth License, Version 1.0" -- a
shortening (Captain Bob, 2026-11-08: "License file SL I think I shortened
accidently"); LICENSE is, and has been since the first commit, the
Starship License 1.0 (SL-1.0, SPDX LicenseRef-Starship-1.0). 349 files,
566 occurrences, now "Starship License, Version 1.0 (SL-1.0)".

Left as they are, pending a ruling: docs/patent/ (the patent figures),
docs/formal/ (the citable volumes) and the generated reports under
docs/working/experiments/ (32 files). Comments and license text only:
the amd64 kernel builds, every changed script parses.
