Slice: Docker-related host labeling (detectable only)

[zoldyzdk]

Parent PRD

#1

What to build

Add lightweight labeling for Docker-related host processes when inferable from host-side metadata (for example command/cgroup hints), without introducing full Docker lifecycle integration.

Acceptance criteria

• When metadata suggests Docker involvement, affected rows include a clear Docker-related label.
• Labeling gracefully degrades when metadata is unavailable or ambiguous.
• No hard dependency on Docker APIs/daemon is introduced for this slice.
