/**
* Registers the peptide custom post type and associated taxonomies.
*
* What: Defines the peptide CPT with REST support, archive, and monograph meta fields.
* Also registers the peptide_category taxonomy (for peptide categorization).
* Who calls it: PR_Core::init() on plugins_loaded.
* Dependencies: None.
*
* Ownership: As of v0.2.0, PR Core is the canonical owner of the `peptide` CPT
* and `peptide_category` taxonomy (previously registered by Peptide Search AI
* pre-schema-sprint; PSA v4.5.0 drops its registrations in favor of this one).
* Registration is guarded by `post_type_exists()` / `taxonomy_exists()` so
* deploy order between the two plugins does not matter — whichever runs first
* wins, the other no-ops.
*
* As of v0.3.0, `peptide_topic` taxonomy is registered in a separate class
* (PR_Core_Topic_Taxonomy) for linking blog posts to peptides via a shared
* topic slug (e.g., 'bpc-157'). This enables the Related Articles feature.
*
* @see ARCHITECTURE.md — CPT specification and post-meta field definitions.
* @see CONVENTIONS.md — CPT ownership rule (no plugin registers a CPT another plugin owns).
