Add tests/llmE2e.test.ts — 7 end-to-end tests driving the REAL
moderation prompt pipeline (buildSystemPrompt → XML payload → llmChat
→ parseModerationResponse) against a live model via omniroute.
Covers: clean technical content (no false positives), harassment
(flagged), username-only offenses including 'Pecinta Pria' +
sexual/provocative usernames + SARA-in-username (always warn/low,
NEVER delete — the nickname-reset path), and spam bursts.
Gated behind AI_LLM_BASE_URL + AI_LLM_API_KEY: CI (no creds) skips
the file → 216 unit tests stay green, zero LLM cost. Run locally via
pnpm test:e2e:live (scripts/run-llm-e2e.sh injects creds from bws).
Verified: 223/223 tests pass with live LLM, stability across 4 runs,
typecheck + biome clean. docs: TESTING.md. ignore .hermes/ plans.
