 - Agents/tool-result truncation: preserve important tail diagnostics by using head+tail truncation for oversized tool results while keeping configurable truncation options. (#20076) thanks @jlwestsr.

 - `web_search` calls your configured provider and returns results.
-  - **Brave** (default): returns structured results (title, URL, snippet).
-  - **Perplexity**: returns AI-synthesized answers with citations from real-time web search.
-  - **Gemini**: returns AI-synthesized answers grounded in Google Search with citations.
 - Results are cached by query for 15 minutes (configurable).
 - `web_fetch` does a plain HTTP GET and extracts readable content
   (HTML → markdown/text). It does **not** execute JavaScript.
 - `web_fetch` is enabled by default (unless explicitly disabled).
