Adopt reusable CI standard + 300-line cleanup (#33)

* ci: adopt reusable CI + 300-line compliance for v4.7.0

- Replace per-repo CI jobs with thin reusable caller
  (peptide-e2e ci.yml@main; tests:stubs, has_js:true)
- Add permissions: contents: write (required for phpcbf auto-commit)
- deploy.yml: drop file-existence + PHP-syntax redundancy; keep PSA_VERSION check
- class-psa-admin.php: remove 37 dead backward-compat proxy lines (327→290)
- class-psa-ai-generator.php: remove 17 dead backward-compat proxy lines (309→292)
- class-psa-search.php: remove 13 dead backward-compat proxy lines (307→294)
  All three files now comply with the estate 300-line rule.
  Zero external callers of removed methods confirmed.
- package.json / package-lock.json: minimal npm manifest for lint-js npm ci step
- ARCHITECTURE.md: update ci.yml description
- PSA_VERSION: sync constant (was 4.5.0) with header (was 4.6.0) → both 4.7.0

Agent-Session: claude-sonnet-4-6-adopt-ci-20260616

* style: auto-fix PHPCS violations via phpcbf

* fix(tests): restore tested proxy methods in PSA_AI_Generator

AIGeneratorTest accesses build_validation_prompt() and
build_generation_prompt() via ReflectionClass - confirmed by running CI.
Restored both as compact single-docblock proxies to PSA_AI_Content.
Condensed section headers to keep file under 300 lines (now 299).

+## [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.
