feat(agent): configurable timeouts for auxiliary LLM calls via config.yaml (#3597)

Add per-task timeout settings under auxiliary.{task}.timeout in config.yaml
instead of hardcoded values. Users with slow local models (Ollama, llama.cpp)
can now increase timeouts for compression, vision, session search, etc.

Defaults:
  - auxiliary.compression.timeout: 120s (was hardcoded 45s)
  - auxiliary.vision.timeout: 30s (unchanged)
  - all other aux tasks: 30s (was hardcoded 30s)
  - title_generator: 30s (was hardcoded 15s)

call_llm/async_call_llm now auto-resolve timeout from config when not
explicitly passed. Callers can still override with an explicit timeout arg.

Based on PR #3406 by alanfwilliams. Converted from env vars to config.yaml
per project conventions.
