merge: resolve main conflict — conserve board smoke (PR #13) + dossier smoke (PR #14)

Conflict: CHANGELOG.md (add/add) and package.json (v1.1.0 vs v1.2.0).

Resolution:
- CHANGELOG.md: keep both entries, v1.2.0 above v1.1.0 (chronological order).
  Updated v1.2.0 description to reference v0.19.2 / v0.19.3 (hotfix context).
- package.json: use version 1.2.0 (PR #14 head; dossier smoke is the newer addition).
- tests/03-admin-plugins.spec.ts: auto-merged by git — board describe block (PR #13)
  at line 97, dossier describe block (PR #14) at line 158. Both conserved.

Dossier smoke selector #prab-dossier verified against v0.19.3 template
(templates/admin/dossier-page.php line 62/86) — registration parent change
does not affect markup.

+# Changelog
+
+All notable changes to the peptide-e2e smoke suite will be documented here.
+
+## [1.2.0] - 2026-06-12
+
+### Added
+- **Dossier page smoke test** (`03-admin-plugins.spec.ts` — `WP Admin — PRAutoBlogger Article Dossier`).
+  Navigates to `/wp-admin/admin.php?page=prautoblogger-dossier&post_id=<N>`, asserts HTTP 200,
+  `#prab-dossier` container visible, body does NOT contain "Invalid plugin page" or "Fatal error".
+  Guards against: menu-ordering regression (wrong hookname → wp_die 404), PHP fatals on dossier
+  load, missing dossier container, and stage-section regression.
+
+  Defensive strategy: tries canonical staging post IDs 925/930 first, then falls back to the
+  most recent REST post, then falls back to post_id=0 (graceful empty state). Stage-section
+  assertions are conditional on a run record existing. Loud test.info() annotations on fallback
+  paths. New in PRAutoBlogger v0.19.2 / v0.19.3.
+
+## [1.1.0] - 2026-06-12
+
+### Added
+- **Board page smoke test** (`03-admin-plugins.spec.ts` — `WP Admin — PRAutoBlogger board page`).
+  Navigates to `/wp-admin/admin.php?page=prautoblogger-board`, asserts HTTP 200,
+  `#prab-board` container visible, and body does NOT contain "Invalid plugin page".
+  Guards against the v0.19.1 regression class: Board submenu registered before parent
+  menu existed (both at admin_menu priority 10) → WordPress fallback hookname →
+  wp_die 404. Now in the deploy-gate smoke suite so this failure class is un-shippable.
+
+  Note: cannot be validated against prod until v0.19.1 of PRAutoBlogger deploys.
+  Spec compiles and lists cleanly under `npx playwright test --list`.
+
+## [1.0.0] - 2026-06-11
+
+Initial release. 21 tests across 5 specs: homepage, reconstitution calculator,
+peptide search, admin plugins, REST API.
