ci: adopt shared reusable deploy workflow (deploy-app.yml)

Replaces the per-repo staging/smoke/production jobs with one call to
peptiderepo/peptide-e2e/.github/workflows/deploy-app.yml (target_path=wp-content/plugins/peptide-repo-core).
Validated end-to-end on the calculator pilot.

 All notable changes to Peptide Repo Core are documented here.
 Format: [Semantic Versioning](https://semver.org/).
 
+## [0.5.0] — 2026-04-27
+
+### Added
+- **Repo Daily CPT**: New `repo_daily` custom post type at `/daily/[slug]/` for editorial publications (articles, guides, comparisons, news) generated by PRAutoBlogger and published under the Boo Sheeran byline.
+- **Repo Daily Category Taxonomy**: Non-hierarchical `repo_daily_category` taxonomy with four seeded terms (article, guide, comparison, news) for editorial classification.
+- **Repo Daily Meta Fields**:
+  - `_repo_daily_author` (string, default "Boo Sheeran") — byline displayed in theme templates. Never hardcoded; always read from meta.
+  - `_repo_daily_clinical_review_required` (bool, stored as '1'/'') — editorial flag marking posts that require PR Clinical Review before publication.
+- **Repo Daily Admin Meta Box**: "Article Settings" meta box on repo_daily edit screen with author byline field and clinical review flag checkbox.
+- **Bulk Author Migration**: On activation, sets `_repo_daily_author = 'Boo Sheeran'` on all post_type=post posts bearing the psa_source meta key (autoblogged articles). Idempotent; existing meta values preserved. Posts remain post_type=post; forward-only migration for byline retroactivity.
+
+### Changed
+- `PR_Core_Admin::register_hooks()` now registers repo_daily metaboxes alongside peptide metaboxes.
+
+### Technical
+- New classes: `PR_Core_Repo_Daily_CPT`, `PR_Core_Repo_Daily_Taxonomy`, `PR_Core_Repo_Daily_Metaboxes`.
+- New method: `PR_Core_Activator::migrate_autoblogged_author_meta()` — idempotent bulk meta setter.
+- Taxonomy seeding: `PR_Core_Repo_Daily_Taxonomy::seed_terms()` called on activation.
+
+### Documentation
+- ARCHITECTURE.md: Added repo_daily CPT to content-type table; documented scanner exclusion by CPT separation.
+- CONVENTIONS.md: Added "How to add a new post meta field to repo_daily posts" extension pattern.

+## How To: Add a New Post-Meta Field to Repo Daily Posts
+
+1. Define the meta key (start with `_repo_daily_`) and sanitization logic (use `sanitize_text_field()` for strings, cast to bool for checkboxes).
+2. Create a new metabox or extend `PR_Core_Repo_Daily_Metaboxes::render_meta_box()` in `admin/class-pr-core-repo-daily-metaboxes.php`.
+3. In `PR_Core_Repo_Daily_Metaboxes::save_meta()`, handle the field: read from `$_POST`, sanitize, and call `update_post_meta()`.
+4. Example: The `_repo_daily_clinical_review_required` checkbox checks for `isset( $_POST['key'] )` and stores `'1'` or `''`; `get_post_meta()` is type-safe because the value is always one of two strings, never a bool.
