lsr911 9dee9ebffa fix(qa-lab): use truncateUtf16Safe for tool search gateway and mock OpenAI text truncation (#103219 )

* fix(qa-lab): use truncateUtf16Safe for tool search and mock OpenAI text truncation

Replace naive .slice(0, N) with truncateUtf16Safe() in:
- tool-search-gateway.fixture.ts: 4 sites (provider input snippet,
  tool output snippet, gateway output text for normal/code lanes)
- mock-openai/server.ts: 1 site (tool output evidence snippet)

LLM output text may contain non-BMP characters (emoji, CJK
extension characters). Naive .slice(0, N) at a surrogate pair
boundary produces a lone surrogate.

* test: add proof script for qa-lab UTF-16 safe truncation at all boundaries

* test(qa-lab): integrate UTF-16 boundary coverage
