netbox-osp v0.2.2 — PyPI README refresh + demo walkthrough

Metadata-only patch so the PyPI project page actually shows the v0.2 features.

Fixed on PyPI

• README screenshots converted from relative docs/screenshots/*.png paths to absolute raw.githubusercontent.com/... URLs so they render inline on the PyPI project page (the v0.2.0 and v0.2.1 releases had broken image icons there).

New on the docs site

• 8-step demo walkthrough — narrative tour of the plugin running against the live demo, with 10 screenshots captured live (OSP model, splice closures, loss-budget gauge, MTP harness deploy form, visual core tracer, plant map).
• README adds a demo walkthrough badge linking to the page.

No code changes. pip install -U netbox-osp is metadata-only.
