Apply GH-DEC-2026-017 to the Taxonomy layer declaration and close RMASTER-WP-0027.

INTENT.md governs; layer.yaml is marked derived from it. standard_version is
removed from both. The value Taxonomy is unchanged: the ruling closes the
vocabulary at four tokens and Taxonomy is one of them. ADR-0010 amended by
revision (accepted-2). No checker in this repository reads the declaration.
