test(cpt): update rest_namespace assertion — now absent, defaults to wp/v2

Merges feature/related-articles-section.

Adds peptide_topic taxonomy, provider interface, internal posts provider, card grid renderer, admin settings, CSS, and unit tests.

Reviewed: qa-reviews/peptide-repo-core/2026-04-24-a10610ded7df.md
CI: PHP 8.1/8.2/8.3 lint, PHPCS, 300-line check — all green.

 All notable changes to Peptide Repo Core are documented here.
 Format: [Semantic Versioning](https://semver.org/).
 
+## [0.3.2] — 2026-04-25
+
+### Fixed
+- Remove `rest_namespace` from peptide CPT registration. Custom namespace prevented Gutenberg block editor from loading peptide posts for editing (404 on wp/v2 REST route). All 89 peptide entries are now editable in the block editor. (#5)
+
+## [0.3.1] — 2026-04-24
+
+### Fixed
+- Add missing `PR_Core_Related_Posts_Provider` interface file (`class-pr-core-related-posts-provider.php`).
+  Omitted from v0.3.0 deploy caused a fatal on every page load. Site was down until this fix.
+
 ## [0.3.0] — 2026-04-24
 
 ### Added
