MCM: fix auto-detection of vLLM binary cache

  _has_artifact_compile_range_with_triton() only checked for a triton/
  subdirectory, which cannot exist when the artifact is a packed binary
  file. Recognize binary artifact_compile_range_* files as valid vLLM
  cache indicators so detect_cache_mode() returns 'vllm' instead of
  falling through to 'triton'.

  Also:
  - sync requirements.txt with pyproject.toml (typer[all], structlog)
  - silence pylint R0903 on Pydantic data models
  - disable pylint import-error for declared but not-installed deps
