ci: integrate vLLM inference tests with GitHub Actions workflows

Add vLLM provider support to integration test CI workflows alongside
existing Ollama support. Configure provider-specific test execution
where vLLM runs only inference specific tests (excluding vision tests) while
Ollama continues to run the full test suite.

This enables comprehensive CI testing of both inference providers but
keeps the vLLM footprint small, this can be expanded later if it proves
to not be too disruptive.
