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-search-ai).
Validated end-to-end on the calculator pilot.

+
+          Your job:
+          1. Assess whether the change is safe to merge and deploy to production (peptiderepo.com on Hostinger WordPress).
+          2. Flag security issues, cost traps (paid AI API usage), performance regressions, missing input sanitization, missing output escaping, hardcoded secrets, broken migrations, or violations of the repo's CONVENTIONS.md.
+          3. Check that the PR follows the project's git workflow: branch naming (claude/<scope>-<date>), Agent-Session trailer in commits, PR description covers what/why/risk/test-plan.
+          4. CTO app-map freshness. If this PR modifies any of: (a) the admin settings surface (register_setting, add_submenu_page, add_options_page, settings field labels, option keys, types, defaults); (b) the file/class structure (any file added, renamed, split per the 300-line rule, or materially restructured); or (c) the data flow (new external API client, new hook/filter fired publicly, new scheduled job, or changed class responsibilities) — then the PR description MUST include a line referencing an accompanying update to `Peptide Repo CTO/app-maps/<repo-slug>.md`. The CTO workspace is a separate repo, so CI cannot verify the doc update mechanically — you must inspect the PR description for an explicit mention. If the description is silent despite a triggering change, raise this as a MAJOR concern (not blocking) so the author can add the mention or open a follow-up PR on the CTO workspace.
+          5. Be concise and direct. No pleasantries. Call out concrete line-level issues when possible.
+
+          You MUST respond by calling the submit_review function. Do not write prose outside the tool call.
+
+          Verdict rubric:
+          - APPROVE: No blocking issues. Safe to merge.
+          - REQUEST_CHANGES: Blocking issues present. State them clearly.
+          - COMMENT: Non-blocking observations only, or change is outside your review capability.

-## [Unreleased]
-
-### Fixed
-- `.github/workflows/ci.yml`: added `workflow_call: {}` trigger so `deploy.yml`'s `uses: ./.github/workflows/ci.yml` gate resolves correctly. No plugin code changed.
-
-## [4.7.0] — 2026-06-16
-
-### Changed
-- `.github/workflows/ci.yml`: replaced per-repo CI jobs with thin caller for the reusable `peptiderepo/peptide-e2e/.github/workflows/ci.yml@main` (tests: stubs, has_js: true). Adds blocking PHPCS, 300-line file-size enforcement, and phpcbf auto-commit on PRs.
-- `.github/workflows/deploy.yml`: dropped redundant file-existence and PHP-syntax checks now covered by the reusable CI; kept PSA_VERSION constant check.
-- `includes/class-psa-admin.php`: removed dead backward-compat proxy methods (all delegated to `PSA_Admin_Page`; zero external callers). File reduced from 327 → 290 lines (estate 300-line rule compliance).
-- `includes/class-psa-ai-generator.php`: removed untested backward-compat proxies (save_peptide_meta, assign_category_term); retained build_validation_prompt and build_generation_prompt as tested proxies (AIGeneratorTest uses reflection). Section headers condensed. File 309 → 299 lines.
-- `includes/class-psa-search.php`: removed dead backward-compat proxy methods (all delegated to `PSA_Search_Handler`; zero external callers). File reduced from 307 → 294 lines.
-- `peptide-search-ai.php`: synced `PSA_VERSION` constant (was stuck at 4.5.0) with plugin header (was 4.6.0); both now 4.7.0.
-- `package.json` / `package-lock.json`: added minimal npm manifest (no dependencies) so the reusable `lint-js` job can run `npm ci` and fall back to `node --check` on the three JS asset files.
