v0.2.2 — one-line, OS-agnostic Docker run

A small usability patch on top of v0.2.1.

Docker — trivial first run, identical on every OS (#132)

No volume, no flags, same one line on macOS, Linux and Windows:

docker run -p 8080:8080 ghcr.io/omercelikdev/mockifyr

• --root-dir /work is now baked into the image, so no run command needs it (a
  --postgres/--redis/--litedb flag still takes precedence).
• Persistence is docker compose up or a named volume — -v mockifyr-data:/work/mappings —
  no $PWD, no \ line-continuation, no "invalid reference format" on PowerShell.
• The $PWD bind-mount drops to an "advanced: edit stub files on your host" note with the
  per-shell path syntax.

Verified on a locally built image: the zero-arg run serves stubs + the dashboard, and a named
volume persists stubs across a container restart.

Engine parity stays green against the Java WireMock oracle in CI.
