Subject: feat: add configurable request timeout for LLM calls

Local LLMs (LM Studio, Ollama, etc.) often need more than the default
30-second timeout. Added request_timeout config option (in seconds)
to [general] section and HEXAI_REQUEST_TIMEOUT env var.

Original constructor signatures preserved via *WithTimeout variants,
so no test changes required.
