feat(agent): parameterized Ollama timeouts + retries in config.yaml

Add resolve_ollama_settings() to read the 'ollama:' config block:
  ollama:
    timeout: 300            # per-request timeout (s), default 300
    tool_call_retries: 3    # max retries on hallucinated tool names

Timeout precedence: ollama.timeout > litellm.timeout > top-level timeout > 300
Retry precedence: ollama.tool_call_retries > default 3

Changes:
- ollama_adapter.py: resolve_ollama_settings() + all retry/timeout
  functions now resolve from config when not explicitly passed
- config.yaml.example: documented ollama: section
- docs/ollama_tool_call_adapter.md: full configuration documentation
- tests/test_ollama_adapter.py: 15 new tests for resolve_ollama_settings
  (56 total, all passing; 1131 total suite, 0 failures)

+`_ensure_ollama_settings()` injects the resolved timeout into the agent's

+
+### 4. `drop_params` and `api_base` propagation
+
+For `ollama_chat`, LiteLLM rejects `parallel_tool_calls` and does not read
+`OPENAI_API_BASE`. The adapter sets:
+- `litellm.drop_params = True` (drop unsupported params)
+- `OLLAMA_API_BASE` from `OPENAI_API_BASE` (env var + litellm module level)
+- `api_base` in compiler LLM calls (for the `add` path)
+
+## Configuration
+
+All settings are in `config.yaml`, under the optional `ollama:` key:
+
+```yaml
+ollama:
+  timeout: 300              # per-request timeout (s), default 300
+  tool_call_retries: 3      # max retries on hallucinated tool names, default 3
+```
+
+### Timeout precedence (highest to lowest)
+
+1. `ollama.timeout` in `config.yaml`
+2. `litellm.timeout` in `config.yaml` (process-wide)
+3. Top-level `timeout:` in `config.yaml`
+4. Built-in default: **300s**
+
+### Retry precedence
+
+1. `ollama.tool_call_retries` in `config.yaml`
+2. Built-in default: **3**
+
+### Example config for slow hardware
+
+```yaml
+model: ollama_chat/gemma4:12b
+language: en
+parallel_tool_calls: false
+ollama:
+  timeout: 600              # 10 minutes per request
+  tool_call_retries: 5      # more patience for small models
+litellm:
+  drop_params: true
+```
+
+### Environment variables
+
+For Ollama, set in `.env`:
+
+```
+LLM_API_KEY=dummy
+OPENAI_API_BASE=http://your-ollama-host:11434
+```
+
+The adapter automatically propagates `OPENAI_API_BASE` → `OLLAMA_API_BASE`.

 ## Limitations
 
 - Very small models (1B params) may still fail after retries — the
   adapter prevents crashes but cannot fix a model's fundamental inability
   to follow tool-use instructions.
+- The `add` path makes multiple sequential LLM calls (summary +
+  concepts); on very slow hardware the second call may time out. Raise
+  `ollama.timeout` or `litellm.timeout` to accommodate.
 - The adapter does not extract tool-call JSON from `content` (the
   `ollama_chat/` rewrite makes this unnecessary for models that support
-  native tool calling).
-- Timeout handling only injects a default; models that exceed 300s per
-  turn need a higher `timeout` in `config.yaml`.
