fix(auth): survive ERR_ABORTED in login retry — recreate context, 5 attempts with backoff

- Introduce safeClose() helper that ignores 'Target page, context or
  browser has been closed' errors. When Hostinger LiteSpeed aborts a
  connection (net::ERR_ABORTED), Playwright internally marks the context
  as closed; the previous bare context.close() threw from inside catch,
  propagating out and killing setup before remaining retries ran.
- MAX_ATTEMPTS 3 → 5 for more tolerance of burst throttle windows.
- Backoff changed from flat 15 s → exponential 5/10/20/40 s (75 s total).
- Worst-case timing: 5 × 90 s nav + 75 s backoff = ~525 s < 900 s job limit.
- Final-failure message explicitly names the LiteSpeed throttle hypothesis.
- Version bump 1.2.0 → 1.3.0.

+# Changelog
+
+All notable changes to the peptide-e2e smoke suite will be documented here.
+
+## [1.3.0] - 2026-06-12
+
+### Fixed
+- **Auth setup survives `ERR_ABORTED` on wp-login.php** (`global.setup.ts`).
+  When Hostinger's LiteSpeed throttles a GitHub runner IP, `page.goto` can
+  throw `net::ERR_ABORTED` rather than a `TimeoutError`. Playwright marks the
+  browser context closed internally on abort, so the existing
+  `context.close()` call in the catch block threw
+  `"browserContext.close: Target page, context or browser has been closed"`,
+  which propagated out of catch and killed setup before the remaining retries
+  ran. Two production deploys were blocked by this flake on 2026-06-12.
+
+  Fix: introduced `safeClose()` helper that swallows the already-closed
+  error, so an aborted context never terminates the retry loop. Max attempts
+  raised from 3 → 5; backoff is now exponential (5 s / 10 s / 20 s / 40 s)
+  instead of a flat 15 s, giving the throttle window more time to clear.
+  Worst-case timing: 5 × 90 s navigation + 75 s backoff = ~525 s, well under
+  the 900 s (15 min) job timeout. Final-failure message explicitly names the
+  LiteSpeed throttle hypothesis so future CI logs self-diagnose.
+
+## [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.
