Move docs/coding-cli-setup.md to docs/coding-cli-setup/ with one file
per CLI (claude-code, kimi-cli, opencode, qwen-code) plus a shared
index.md for the gateway intro, tool-calling risk note, and summary
table.
Also fixes the qwen-code doc: context sizes are per-slot
(LLAMA_CTX_SIZE / LLAMA_PARALLEL), not raw LLAMA_CTX_SIZE (same fix
applied to OpenCode's limit.context); documents the fastModel
classifier provider and its own context math; adds the omniroute-search
MCP server (SearXNG web search) and Auto Mode permissions tuning that
were missing from the original qwen-code section.
