Drops PSA registration of peptide CPT + peptide_category taxonomy (PR Core >= 0.2.0 now owns them per 2026-04-22 consolidation). Adds hard dependency check on PR Core 0.2.0+ — PSA self-deactivates with an admin notice if PR Core is missing or below min version.
CI note: PHPUnit failures (PSA_AI_Content, PSA_Directory_API not found) and WPCS failure are pre-existing on main at HEAD 65f973f (verified: same 5 errors in run 24530495421). PHP Lint green on 7.4/8.1/8.3. No regressions introduced by this PR.
QA: qa-reviews/2026-04-22-2609c66.md PASS.
Adds [peptide_directory] shortcode with card grid, category taxonomy (8 terms),
search, pagination, detail modal, and /v1/compounds REST endpoint. Includes 9
new meta fields (half-life, stability, solubility, etc.), admin data tools for
migration/re-enrichment, integration hooks for cross-plugin extensibility,
dark mode support, and full uninstall cleanup. Refactors AI generator into
PSA_OpenRouter + PSA_KB_Builder classes. Adds PHPUnit tests for PostType and
Directory classes. Fixes QA findings: dead JS selector, renderError loading
state, numeric meta validation, prepared SQL in uninstall.
