[Pukujan]: Done in #57 (merged as 91c84f6). Tested on a 4017 test proxy; the live :4000 proxy is being restarted once to pick up the new chain.

Context: GitHub issue Pukujan/claude-code-launcher#56 (closed, 1 comments, reported 2026-10-04): WebSearch currently runs `searxng,ddgs,tavily,exa`. Add two more free sources ahead of the paid ones: - **TinyFish Search**: LiteLLM's native `tinyfish` search provider (LiteLLM 1.90.0+; the pinned 1.103.0 has it). Reads `TINYFISH_API_KEY`. Free tier, 30 requests/min. - **You.com, no key**: LiteLLM's native `you_com` provider. With `YOUCOM_API_KEY` unset it uses You.com's keyless free tier (IP-throttled, 100 queries/day). New chain: `searxng,tinyfish,ddgs,you_com,tavily,exa`. Keys keep coming from the desktop env through `CCL_ENV_ALIASES` (`TINYFISH_API_KEY [your value] only names go in `.env.l
