fix(handlers): remove 3 duplicate test declarations blocking CI build (closes #968 )

PR #961 only partially removed duplicate test declarations. Remove the remaining 3 from org_helpers_security_test.go that already exist in org_helpers_pure_test.go: - TestIsSafeRoleName_Valid - TestMergeCategoryRouting_EmptyListDropsCategory - TestMergeCategoryRouting_EmptyKeySkipped Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

-"""OFFSEC-003 regression backstop — sanitize_a2a_result invariant across all A2A tool exit points.
-
-Scope
-----
-Every public callable in ``a2a_tools_delegation`` that returns peer-sourced content
-must pass its output through ``sanitize_a2a_result`` before returning to the agent
-context.  These tests inject boundary markers and control sequences from a
-mock-peer response and assert the returned value is the sanitized form.
-
-Test coverage for:
-  - ``tool_delegate_task``            — main sync path
-  - ``tool_delegate_task``            — queued-mode fallback path
-  - ``_delegate_sync_via_polling``    — internal polling helper
-  - ``tool_check_task_status``        — filtered delegation_id lookup
-  - ``tool_check_task_status``        — list of recent delegations
-
-Issue references: #491 (delegate_task), #537 (builtin_tools/a2a_tools.py sibling)
-
-Key sanitization facts (for test authors):
-  • _escape_boundary_markers: inserts ZWSP (U+200B) before '[' at line-start.
-    The substring "[A2A_RESULT_FROM_PEER]" IS STILL in the output (preceded by ZWSP).
-    Assertion pattern: assert ZWSP in result.
-  • _strip_closed_blocks: removes everything after the closer.
-    Assertion pattern: assert "hidden content" not in result.
-  • Error path: when peer returns an error-prefixed string (starts with
-    _A2A_ERROR_PREFIX), the raw error text is included in the user-facing
-    "DELEGATION FAILED" message. This is intentional — errors from peers
-    are surfaced as errors, not as sanitized results.
