Ollama: verify model pulled before marking installed

[himanshu231204]

Background

After ollama pull, a race can report success before the model is listed.

Why it matters

False success leads to confusing later failures.

Acceptance criteria

• Confirm the model appears in ollama list before reporting success.
• Retry once on race with a short backoff.
• Add an -m integration test (skips without Ollama).

Where to look

• src/modeldock/adapters/runtimes/ollama.py, src/modeldock/core/manager.py
