feat: v0.4.0 — welle A (8 new tools: container lifecycle, inspect_image, system_overview)

Closes #1, #4, #6, #7.

Container lifecycle (#1, #7):
- start_container, stop_container, restart_container, pause_container,
  unpause_container — all via SYNO.Docker.Container with JSON-encoded
  name parameter, routed through _resolve_container_name for hash-
  prefix resolution. stop is live-verified; the other four are
  implemented by symmetry on the same API surface.

inspect_image (#4):
- Returns full image detail (layers, env, ports, entrypoint/cmd,
  labels) via SYNO.Docker.Image/get. Accepts name:tag, registry-
  prefixed names, and bare hashes. Defensive response parsing
  handles both wrapped (details.*) and flat envelopes.

system_overview (#6):
- Aggregates CPU %, RAM, network and block I/O across all running
  containers plus running/stopped counts. No new DSM endpoint —
  composed from list + stats, reusing the container_stats CPU
  formula. Per-source errors are non-fatal.
