fix(handlers): replace time.Sleep with explicit async drain in 1 test (issue #1264 )

Issue #1264: CI/Platform(Go) tests flake under parallel CI load. TestProxyA2A_AllowedSelf_SkipsAccessCheck uses time.Sleep(50ms) to wait for goroutines launched by goAsync() — same pattern as the 4 tests fixed in PR #1282. Replacing with handler.waitAsyncForTest() ensures deterministic async completion regardless of runner speed/pressure. Also fixes the sop-checklist test file (parse_directives tuple return type mismatch) that was committed in broken state to PR #1284. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
fix(sop-checklist): skip blank lines when scanning for section content

+# E2E test: workspace broadcast and talk-to-user platform abilities.
+#
+# What this proves:
+#   1. talk_to_user_enabled (default true) — POST /notify works out-of-the-box.
+#   2. PATCH /workspaces/:id/abilities { talk_to_user_enabled: false } disables
+#      delivery: /notify → 403 with error="talk_to_user_disabled" + delegate hint.
+#   3. Re-enabling talk_to_user_enabled restores delivery.
+#   4. broadcast_enabled (default false) — POST /broadcast → 403 when disabled.
+#   5. PATCH { broadcast_enabled: true } enables fan-out.
+#   6. POST /broadcast delivers to all non-sender, non-removed workspaces:
+#      - Returns {"status":"sent","delivered":N}
+#      - Receiver's activity log has a broadcast_receive entry with the message.
+#      - Sender's activity log has a broadcast_sent entry.
+#   7. The sender itself does NOT receive a broadcast_receive entry.

Never paste file URLs in the message body — always pass absolute paths in `attachments` so the platform serves them as download chips (works on SaaS where external file hosts are unreachable).
