test(skills): implement Assassin Milestone M29 Class Gate & End-to-End Suite (30/30 skills)

- Add adv-ass-e2e-gate.test.ts covering all 8 core cross-tree scenarios: 1. Traps Tree Synergy Network & 5-Band Progression (LS +720%, DS corpse explosion, Blade weapon scaling 3/8 and 3/4). 2. Martial Arts Charge-Up & Finisher Discharge Pipeline (multi-skill charges, single-tier Phoenix Strike, Dragon Talon multi-kicks, Dragon Claw dual strikes). 3. Shadow Disciplines Buff Mechanics & Venom Bitrate Clamp (BoS vs Fade cancellation, Venom 10-frame clamp, CoS recast lockout). 4. Minion & Summon Caps (5 Traps + 1 Shadow = 6 Max concurrent pets). 5. NextDelay Collision Avoidance Across Trees (WoF 4f, Shock Web 25f, Dragon Flight 4f). 6. Cross-Tree Hybrid Build Integration (Trapper / Kicksin / Shadow). 7. Crowd Control & Status Effects (Mind Blast 4y stun/conversion, Psychic Hammer KB, CoS blind). 8. Complete 30-Skill Assassin Tree Data Registry & Invariants (IDs 251..280 exist in D2DataRegistry, BATCH1_SKILLS length = 38). - All 34 Assassin test files pass (166/166 tests passed). - TypeScript Typecheck (tsc --noEmit) passes with 0 errors.

+ *
+ * Core Verification Scenarios:
+ * Scenario 1: Traps Tree Synergy Network & 5-Band Progression (Traps)
+ * Scenario 2: Martial Arts Charge-Up & Finisher Discharge Pipeline
+ * Scenario 3: Shadow Disciplines Buff Mechanics & Venom Bitrate Clamp
+ * Scenario 4: Minion & Summon Caps (5 Traps + 1 Shadow = 6 Max)
+ * Scenario 5: NextDelay Collision Avoidance Across Trees
+ * Scenario 6: Cross-Tree Hybrid Build Integration (Trapper / Kicksin / Shadow)
+ * Scenario 7: Crowd Control & Status Effects (Mind Blast Stun/Convert, Psychic Hammer KB, CoS Blind)
+ * Scenario 8: Complete 30-Skill Assassin Tree Data Registry & Architectural Invariants
+ *
+ * ZERO MOCKS: vi.mock / vi.spyOn strictly forbidden.
+ * ZERO CIRCULAR ORACLES: Precalculated independently from 1.13c ground truth constants.
