* fix(web_search): add timeout floor and retry for Volcengine provider
Volcengine's Responses API pipeline (web search + model inference +
JSON generation) can exceed the default 15 s timeout on complex
queries, causing ~50% of requests to fail with transport errors.
Changes:
- Enforce a 60 s minimum timeout for the Volcengine provider
- Separate connect_timeout (15 s) from total request timeout
- Retry transient transport errors up to 3 times (1 s / 2 s backoff)
- Add TCP keepalive, HTTP/2 keepalive, and User-Agent headers
matching the patterns used in client.rs
