…e URL Supports container deployments where Ollama runs on a Docker network host (e.g. http://ollama:11434) without requiring config.toml changes. Includes regression test ensuring the environment override works.

Feature
Add support for configuring the Ollama context window via environment variable.
Environment variable:
ZEROCLAW_OLLAMA_NUM_CTX
If set, the value is forwarded to the Ollama
/api/chatrequest asoptions.num_ctx.Motivation
Ollama defaults to a 4096 context window when
num_ctxis not provided.This prevents full utilization of larger models on systems with sufficient VRAM.
This change allows deployments to configure larger contexts (e.g. 32k) without modifying source code.
Example
docker-compose:
environment:
ZEROCLAW_OLLAMA_NUM_CTX=32768
Result
Requests sent to Ollama include:
options:
num_ctx: 32768
