End-to-End Pipeline Test: init_gate -> agi_reason -> asi_empathize -> apex_verdict -> vault_seal

This is the single most important test in arifOS. It proves the core claim:
a query enters the system, passes through all three engines (AGI/ASI/APEX),
receives a constitutional verdict, and gets sealed in the ledger.

Uses the v55 canonical tool handlers directly (not old v53 aliases).
