🤖 ci: split Ollama tests into separate job

Separates Ollama integration tests from main integration test suite:

**New Job: ollama-test**
- Dedicated job for Ollama-specific tests
- Sets up Ollama binary and model cache
- Runs only tests/ipcMain/ollama.test.ts
- Uploads coverage with 'ollama-tests' flag

**Updated Job: integration-test**
- Removed Ollama setup steps
- Excludes ollama.test.ts via --testPathIgnorePatterns
- Removed OLLAMA_BASE_URL env var
- Faster execution without Ollama dependencies

Benefits:
- Better parallelism (Ollama tests run independently)
- Clearer separation of concerns
- Main integration tests complete faster
- Ollama-specific caching isolated to one job
