LiteLLM Global-tools entry: frame granite-4.1-8b as the standing
always-available local summarizer/classifier endpoint (FP8, ana-ml2 GPU1,
131k ctx); add qwen3.5-9b-fp8 (vision) to the gateway listing; document the
shared all-agents virtual key (alias all-agents-local) scoped to the free
local models only (granite/vision/embed/rerank; paid GLM walled off).
Internal-only gateway, rotatable.
Global Claude Code preferences (symlinked from ~/.claude/CLAUDE.md, like
the other home_root dotfiles). Includes the new 'Global tools available'
section documenting box-wide Playwright/Chromium on nh3-dev.
